6.1 Products must be accepted by the manufacturer's technical control service for compliance with the requirements of this standard, as well as the conditions specified in the contract for the manufacture and supply of products. Confirmation of acceptance of products by the technical control service of the manufacturer is the execution of documents on the acceptance (quality) of products. Products are accepted in batches or individually. When accepting products at the manufacturing plant, a lot is taken as the number of products manufactured within one shift and issued with one quality document. The number of products of the same design, manufactured according to one order, can be taken as the batch size. 6.2 The requirements for product quality established in this standard are confirmed by: incoming inspection of materials and components; operational production control; acceptance control of finished products; control acceptance tests of a batch of products conducted by the quality control service of the manufacturer; periodic and certification tests of products in independent testing centers; qualification tests. 6.3 The procedure for conducting incoming control and operational production control at workplaces is established in the technological documentation. If the manufacturer completes the door blocks with accessories own production, then they must be accepted and tested in accordance with the requirements of the regulatory documentation for these products. 6.4 Acceptance control of the quality of finished products is carried out by the method of continuous control. The list of controlled indicators is given in table 8. Finished products that have passed acceptance control are marked. Products that have not passed the acceptance control for at least one indicator are rejected. Table 8

* Test type I - acceptance tests during acceptance control; test type II - acceptance tests conducted by the quality service of the manufacturer; test type III - periodic tests carried out in independent test centers. ** Controlled nominal dimensions for test type II are set in the technological documentation.

6.5 Each batch of products undergoes control acceptance tests conducted by the quality service of the manufacturer. The list of controlled indicators and the frequency of control are given in Table 8. For testing, samples of door blocks are taken from a batch of products by random selection in the amount of 3% of the batch volume, but not less than 3 pcs. If there are less than 3 products in a batch, each product is subjected to control. In the event of a negative test result for at least one indicator on at least one sample, a re-check of the quality of products is carried out on a double number of samples for the indicator that had a negative test result. If a discrepancy between the indicator and the established requirements is detected again, at least on one sample, the control and subsequent batches of products are subjected to continuous control (sorting). With a positive result of continuous control, they return to the established procedure for acceptance tests. 6.6 Periodic tests according to the performance indicators specified in 5.3.1 - 5.3.7 are carried out when they are put into production or when changes are made to the design of products or their manufacturing technology, but at least once in the period specified in Table 8, and also when product certification. In justified cases, it is allowed to combine periodic and certification tests. Qualification tests of products are carried out for all indicators when putting products into production. Tests are carried out in test centers accredited for the right to conduct them. Tests to determine the reduced resistance to heat transfer, air permeability, sound insulation are subjected to structures designed to withstand these loads according to their field of application. 6.7 The consumer has the right to conduct a quality control check of products, while observing the sampling procedure and test methods specified in this standard. When products are accepted by the consumer, a batch is considered to be the number of products shipped for a specific order, but not more than 90 pieces, drawn up with one quality document. 6.8 When accepting products by the consumer, it is recommended to use the one-stage quality control plan for products given in Table 9. Table 9

Note - Significant and critical defects include: defects leading to loss of performance, unrecoverable without replacing part of the product (breakage of the steel profile, etc.), exceeding the maximum deviations of dimensions by more than 1.5 times established in the RD, disassembly of products. Minor defects include removable defects: minor surface damage, unadjusted door appliances and hinges, exceeding the limit deviations of dimensions by less than 1.5 times established in the ND. By agreement of the parties, acceptance of products by the consumer can be carried out at the manufacturer's warehouse, at the consumer's warehouse or in another place specified in the supply contract. 6.9 Each batch of products must be accompanied by a quality document (passport). An example of filling out the product passport is given in Appendix D. 6.10 Acceptance of products by the consumer does not relieve the manufacturer from liability in case of detection hidden defects that led to a violation of the performance characteristics of products during the warranty period.

7 Control methods

7.1 The methods of incoming and production operational quality control are established in the technological documentation. 7.2 Methods for quality control of products during acceptance control and acceptance tests 7.2.1 The geometric dimensions of products, as well as the straightness of the edges, are determined using the methods established in GOST 26433.0 and GOST 26433.1. Limit deviations from the nominal dimensions of product elements, the difference in the lengths of the diagonals and other dimensions are determined using a metal measuring tape according to GOST 7502, a caliper according to GOST 166, and probes according to ND. The maximum deviations from the straightness of the edges are determined by applying a calibration ruler in accordance with GOST 8026 or a building level with a flatness tolerance of at least the 9th degree of accuracy in accordance with GOST 9416 to the tested part and measuring the largest gap using feelers according to ND. 7.2.2 The maximum deviations from the nominal dimensions of the gaps under the overlay are checked using a set of probes or a ruler in accordance with GOST 427. mating surface to the bottom surface. 7.2.4 Appearance, quality of welds, color and quality of finishing of products are evaluated visually by comparison with standard samples approved in the prescribed manner. Surface defects visible to the naked eye from a distance of 1.5 m in natural light of at least 300 lux are not allowed. 7.2.5 Adhesion (strength of adhesion of paint and varnish coatings to the metal surface) is determined by the method of lattice cuts according to GOST 15140. packaging is checked visually. To determine the tightness of sealing gaskets, compare the dimensions of the gaps in the porches and the degree of compression of the gaskets, which should be at least 1/5 of the height of the uncompressed gasket. Measurements are made with a caliper or a ruler in accordance with GOST 427. The tightness of sealing gaskets with closed canvases can be determined by the presence of a continuous trace left by a coloring matter (for example, colored chalk), previously applied to the surface of the gaskets and easily removed after inspection. 7.2.7 The operation of the door hinges is checked by opening and closing the wing elements of the product ten times. In case of detection of deviations in the operation of door devices, they are adjusted and re-checked.

7.3 Methods of control during periodic tests 7.3.1 The reduced resistance to heat transfer is determined according to GOST 26602.1. 7.3.2 Air and water permeability is determined according to GOST 26602.2. 7.3.3 Sound insulation is determined according to GOST 26602.3. 7.3.4 Indicators of reliability, resistance to static, dynamic, impact loads are determined according to RD and methods approved in the prescribed manner. When testing for dynamic load resistance, they simulate the load that occurs when the door leaf is suddenly opened (for example, during a draft), at the moment the door leaf contacts the slope of the doorway. The test for impact resistance with a soft inelastic body is carried out with a three-time impact, for example, with a pear with a lower diameter of (300 ± 5) mm and a mass of (30 ± 0.5) kg, from a fall height according to 5.3.5 to the central zone of the sample. Note - At the end of the test, the door blocks must remain operational, while the bolt of the lock and the latch must freely enter their mating parts. Before and after testing the door units for failure-free operation, it is recommended to check the tightness of the seals in accordance with 7.2.6. When testing door blocks for resistance to a static load acting perpendicular to the plane of the leaf in the free corner zone, it is recommended to use the graph of dependence of the deflection of the free corner of the leaf on the applied load given in Appendix D. 7.3.5 Quality control methods for welded joints (5.3. 10) are installed in the manufacturer's technical documentation in accordance with GOST 5264.

The inlet in the door frame for the entry of the bolt shall be cleaned in accordance with 5.8.2.7.

Note - For group A door blocks installed in public buildings, it is recommended to use electromechanical (electronic) locking devices.

5.8.2.11 When mounting the cylinder lock and installing the cylinder mechanism, the length of the cylinder mechanism and the asymmetry with respect to the middle of the leash shall be chosen so that the cylinder mechanism protrudes from the outside of the armor plate by no more than 3–5 mm. When installing the armor plate, the length of the cylinder mechanism is chosen taking it into account.

5.8.2.12 After assembling the door block, make sure that the locks are functioning normally.

5.8.2.13 Finished door blocks should be transported with the locks "open" to prevent possible deformation of the crossbars during transportation.

5.8.2.14 Installation of a door block in an opening should be carried out by manufacturers of door blocks or an organization installing door blocks in accordance with GOST 30971 or regulatory documents that establish requirements for the installation of door blocks in openings. General requirements for the installation of door blocks are given in Appendix D.

Note - When forming the design of the junction mounting units, it is necessary to take into account the scope of the door blocks, the features of the thermal expansion of door frames and door panels, and the requirements for burglary resistance.

5.8.2.15 Before installation, the door unit should be freed from packaging, check that possible packaging residues (especially polyethylene) are not pulled into the gaps between the deadbolt and the lock body.

5.8.2.16 After installing the door unit in the opening, before final sealing, check the operability of the door leaf and locks.

Note - When using mounting foam for sealing, it is necessary to exclude the possibility of its getting into the door frame, into the movement zone of the deadbolt to prevent disruption of the normal functioning of the lock.

5.8.3 Installing a lock in a functioning front door

5.8.3.1 If it is necessary to improve the security properties of a functioning door, an additional lock is installed in a new place on the door leaf.

5.8.3.2 Additional and already installed locks must be different systems secret. If there is a lock with a latch on the door leaf, then the additional lock intended for installation must be without a latch.

5.8.3.3 Before installing an additional lock, inspect the interior of the door leaf (removable panel on the inside, a hatch under the upholstery or a removable wall, etc.) so that when cutting through the door frame, do not get into the reinforcement or partition.

5.8.3.4 Marking for insertion of an additional lock must be carried out according to the scheme included in the delivery set, or according to the dimensions of the lock.

5.8.3.5 The cavity of the niche must be freed from foreign objects and debris so that the lock enters it freely. In order for the new niche not to be isolated from the rest of the cavity of the door leaf, it is necessary to exclude the possibility of foreign objects getting into the lock mechanism during operation of the door, which may affect its normal operation.

5.8.3.6 When mounting the lock, forces and impacts on the cylinder mechanism are not allowed.

5.8.3.7 It is not allowed to drill the walls of the door block to correct the location of the key channel or the cylinder mechanism with a lock inserted into the niche.

5.8.3.8 The hole for the passage of the bolt of the lock into the door frame must ensure the free passage of the bolt while holding the leaf with the latch.

5.8.3.9 When choosing a cylinder mechanism, its reliability class should be taken into account depending on the area of ​​application in accordance with Table 1 of GOST 5089.

5.8.3.10 It is recommended to purchase the cylinder mechanism after installing the lock, considering that the lock may not be installed in the middle part of the door thickness. In this case, the cylinder mechanism must be asymmetrical with respect to the middle of the driver.

Note - The length and symmetry of the cylinder mechanism can be calculated by focusing on the end of the door leaf and the middle of the bolt of the lock, taking into account the end plates. The cylinder mechanism should not protrude from the lining (at least from the outside) by more than 3 - 5 mm. If it is planned to install an armor plate, then the dimensions of the cylinder mechanism are adjusted to take it into account. The installation of an armor plate is desirable, as it increases the resistance of the cylinder mechanism assembly to breaking.

5.9 Malfunction and warranty service of the lock

Violation of the normal operation of the lock, caused by its improper operation, as well as the appearance of any changes in the lock that are not provided for by the design, remove the obligations of the manufacturer (dealer) for warranty service.

Notes

7.2.1 The geometric dimensions of the door blocks and the straightness of the edges are determined using the methods established in GOST 26433.0 and GOST 26433.1.

Limit deviations of the nominal dimensions of product elements, the difference in the lengths of the diagonals and other dimensions are determined using a metal measuring tape according to GOST 7502, a caliper according to GOST 166, probes according to regulatory documents.

Limit deviations from the straightness of the edges are determined by applying a calibration ruler in accordance with GOST 8026 or a building level with a flatness tolerance of at least the 9th degree of accuracy in accordance with GOST 9416 to the part under test and measuring the largest gap using probes according to regulatory documents.

7.2.2 Limit deviations of the nominal dimensions of the gaps under the overlay are checked using a set of probes or a ruler in accordance with GOST 427.

7.2.3 The sag in the mating of adjacent parts lying in the same plane is determined with a feeler gauge as the distance from the edge of the ruler according to GOST 427, applied to the upper mating surface, to the lower surface.

7.2.4 Appearance, quality of welded joints, color and quality of finishing of door blocks are evaluated visually by comparison with standard samples approved by the head of the manufacturer, from a distance of 1.5 m in natural light of at least 300 lux.

7.2.5 Adhesion (strength of adhesion of paint and varnish coatings to the metal surface) is determined by the lattice notch method according to GOST 31149.

7.2.6 The tightness and correct installation of sealing gaskets, door fittings, fasteners and other parts, color and absence of cracks in welded joints, marking and packaging are checked visually.

To determine the tightness of sealing gaskets, compare the dimensions of the gaps in the porches and the degree of compression of the gaskets, which should be at least 1/5 of the height of the uncompressed gasket. Measurements are carried out with a caliper according to GOST 166 or a ruler according to GOST 427.

The tightness of sealing gaskets with closed canvases can be determined by the presence of a continuous trace left by a coloring matter (for example, colored chalk), previously applied to the surface of the gaskets and easily removed after inspection.

7.2.7 The operation of the door hinges is checked by opening and closing the leaf elements of the product ten times. In case of detection of deviations in the operation of the door hinges, they are adjusted and re-checked.

7.3 Methods for determining the indicators controlled during periodic tests are given in 7.3.1 - 7.3.10.

7.3.1 The reduced resistance to heat transfer is determined in accordance with GOST 26602.1.

7.3.2 Air and water permeability is determined according to GOST 26602.2.

7.3.4 Wind load resistance is determined according to GOST 26602.5.

7.3.5 Indicators of reliability, resistance to static, dynamic, shock loads and ergonomic indicators of door blocks are determined according to the methods of testing laboratories, Appendix B of this standard and GOST 30777.

Tests of locking devices for non-failure operation, load resistance and compliance with ergonomic requirements are carried out on special equipment (stands) according to regulatory documents, programs and methods of testing laboratories.

After testing, the product must remain operational.

When testing to determine the resistance to dynamic loads, the load that occurs when the door leaf is suddenly opened (for example, during a draft) at the moment of contact of the door leaf with the slope of the doorway is simulated.

The test to determine the impact resistance of a soft inelastic body is carried out with a three-time impact, for example, with a pear with a diameter of the lower part (300 ± 5) mm and a mass of (30 ± 0.5) kg, from a height of fall according to 5.3.4 into the central zone of the sample. After testing, the residual deformation shall not exceed 2 mm.

At the end of the tests, the door blocks must remain operational, while the deadbolt of the lock and the latch must freely enter their mating parts.

Before and after testing the door units for failure-free operation, it is recommended to check the tightness of the seals in accordance with 7.2.6.

When testing door blocks to determine the resistance to a static load (see Appendix B) acting perpendicular to the plane of the door leaf in the free corner zone, it is recommended to use the graph of free corner deflection versus the applied load given in Appendix A.

When applying a load in the plane of the door leaf, the leaf must be open at 90° with respect to the frame. The load is applied in the area of ​​the free corner, kept for at least 5 minutes. Deformation is analyzed, including tearing of a loop from a web or box.

7.3.6 When testing door blocks to determine the resistance to impact load created by a solid body, a three-time blow is carried out in the center of the door leaf and, if necessary, in the corner zones with a solid body weighing 2 kg. The average value of the impact damage diameter should not exceed 2.0 mm, the depth - 1.5 mm. After testing, the door blocks must remain operational.

7.3.7 Corrosion resistance of metal of door blocks and locking devices is determined in accordance with GOST 9.308, GOST 538 and regulatory documents for specific products.

7.3.8 Lock products must be tested with the subsequent assignment of a class of resistance to opening and breaking in accordance with GOST 5089, GOST 19091, as well as with regulatory documents * (6) in force on the territory of the state party to the agreement that adopted this standard.

7.3.9 Wind loads on door units of group A are measured according to the normative documents for test methods, taking into account the fact that the entrance doors to the buildings are located on the first floors of the buildings. After testing, the deflection value shall not exceed 6 mm. Structural elements must withstand wind loads without damage, the door leaf must be closed (all locking devices must be engaged).

Note - Destruction and replacement of glass or double-glazed windows is allowed.

7.3.10 Quality control methods for welded joints are established in the manufacturer's technical documentation in accordance with GOST 5264.

7.3.11 Burglary test

7.3.11.1 Burglar resistance tests are carried out on door blocks with enhanced protective functions in accordance with the regulatory documents for test methods, including in accordance with the regulatory documents * (4) in force on the territory of the state party to the agreement that adopted this standard. Tests are carried out on door blocks in the direction of opening the door leaf until the sample breaks, i.e. until the door is opened or to a state in which, due to deformation, the web is jammed and further continuation of the test does not make sense.

7.3.11.2 Burglary resistance is determined by the time spent on breaking, and depending on the type of tool used. Requirements for a tool for manual hacking - in accordance with the regulatory documents * (5) in force in the territory of the state party to the agreement that has adopted this standard.

7.3.11.3 The protection class of laminated glass is determined according to GOST 30826.

Methods for determining the resistance to static loads and schemes for applying dynamic loads

B.1 Resistance to static load applied in the plane of the door leaf

B.1.1 When determining the resistance to a static load applied in the plane of the door leaf, the load (sequentially from the smallest to the largest) is applied to the open leaf by 90 ° in the direction from top to bottom in the zone of the free corner (the application point is set) for 5 min.

B.1.2 After removal of the load, the presence (or absence) of permanent deformation is revealed. If the residual deformation fits into half of the gap between the leaf and the frame (in the lower and vertical parts of the door in the area of ​​the free corner) or is completely absent, the door passed the test.

B.2 Resistance to static load applied in the area of ​​the free corner of the door leaf perpendicular to its plane

B.2.1 When determining the resistance to a static load applied in the plane of the door leaf, the load (successively from smallest to largest) is applied in the direction of opening of the door leaf (with the door closed on all locks) in the area of ​​the free corner (the application point is given) in within 5 min.

B.2.2 After the load is removed, the presence (or absence) of permanent deformation is determined. If the permanent deformation (in the area of ​​the free corner) does not exceed 1/5 of the thickness of the seal (see 7.2.6), the door passed the test. Otherwise, a gap will open for the passage of air and the sound insulation and burglary resistance will decrease.

B.3 Resistance to static load applied in the hinge area perpendicular to the plane of the door leaf

B.3.1 When determining the resistance to a static load applied in the area of ​​the hinges perpendicular to the plane of the door leaf, the load (successively from smaller to larger) is applied in the direction of opening of the leaf (while the door must be closed on all locks) in the area of ​​\u200b\u200beach hinge (application points are given ) within 5 min.

B.3.2 After the load is removed, the presence (or absence) of permanent deformation is determined. If the permanent deformation in the area of ​​each hinge does not exceed 1/5 of the thickness of the seal (see 7.2.6), the door passed the test. Otherwise, a gap will open for the passage of air and the sound insulation and burglary resistance will decrease. Schemes for applying dynamic loads are shown in Figures B.1 - B.3.

In the process of choosing a metal front door in the product description, you can find widespread references to the fact that the products are of high quality. Only a knowledgeable and experienced specialist can conduct a detailed analysis of the doors. What about ordinary customers, for whom all front doors for the most part look the same? We recommend paying close attention to the standardization of manufactured products. In the Russian Federation, state standards (GOST) have been developed and approved, indicating technical and other requirements that manufactured products must comply with. To confirm compliance, certificates of conformity of the approved sample are issued. It is believed that buyers who purchase metal entrance doors are fully protected in terms of purchasing and using the highest quality products. Let's take a closer look at the approved standard.

What standard applies to fire doors?

When choosing a high-quality metal fire door, you should adhere to the GOST 31173-2003 standard. It touches steel door blocks with locks general view. It assumes standard fire doors that can be used in residential and industrial premises. At the same time, it is worth knowing that doors of increased security and operational characteristics (explosion resistance, armour, bullet resistance, resistance to numerous aggressive environmental influences, and so on) do not belong to the above standard.

GOST 31173-2003 describes the features of marking, classification of door blocks. At the same time, recommendations are made regarding the use of a certain type of steel. The features of the box, doors, installation of locks and heat-insulating materials are also described. In addition, recommendations are given regarding the finishing of the sash (outer and inner side).

A characteristic feature of the described standard is the fact that the so-called "fire doors" do not directly apply to it. Moreover, there is simply no separate state standard for doors of this type. Therefore, GOST 31173-2003 applies to them by analogy. Mainly, as mentioned above, it describes the design of metal doors. In fact, the situation is as follows. Manufacturer in the manufacture of fireproof metal entrance doors develops its own installations, which are most often referred to as "technical conditions". They provide for performance requirements relating to fire resistance. Such technical conditions (TU) are as close as possible to GOST 31173-2003. In order for manufactured doors to be considered fire resistant, the manufacturer must obtain a special so-called fire certificate. It is valid for three years. After the expiration date, the certificate must be obtained again. The main condition for obtaining such a certificate is testing with a sample of the door produced. Tests are carried out in accordance with the recommendations and rules that are enshrined in the State Standard "Test methods for fire resistance of doors and gates" (number 53307-2009). During the combustibility test in a special oven, one side of the web is heated to the limit values. Upon successful completion of the product test, a certain fire resistance class is assigned, which is recorded in the issued certificate. The higher the class, the more expensive the metal door. Of course, a higher quality and fire-resistant door can be used not only in residential, but also in industrial premises with elevated temperatures.

What determines the fire resistance of a metal door?

There is a fairly widespread opinion, according to which it is considered: the thicker the sheet of a metal door leaf, the more resistant it is to elevated temperatures. This is not true. In fact, the following features are of decisive importance:

1. Heat insulator (heater). GOST 31173-2003 as a heater provides for the possibility of using foam, mineral wool, wood and particle fillers. For obvious reasons, such a heat insulator is not suitable for fireproof metal entrance doors. On sale there are heaters, characterized by high fire resistance. How to insulate the canvas with such material on your own or with the help of a master, read the material dedicated to this.
2. The distance (size) of the gap between the box and the door leaf. Ideally, this parameter should not exceed a value of 3 mm. The greater the deviation from this indicator, the lower the fire resistance of the door block.
3. Self-foaming sealant. An extremely useful material that foams up in the event of a fire. The foam fills the space between the sash and the frame. This allows to some extent to prevent the spread of fire and heating of the door frame and leaf. And also to prevent the ingress of combustion products into the room.
4. Sealing gaskets. Those of them that comply with GOST 31173-2003 should be used. They should tightly cover the entire perimeter of the sash.

How to choose a quality fire door?

The main purpose of a fire door is to protect against the spread of fire for some time before the arrival of rescuers. The main provisions relating to fire safety (including those for doors of this type) are contained in the technical regulation approved by the Federal Law of the Russian Federation No. 123-FZ of July 22, 2008.

When choosing a fireproof metal entrance door, one should pay attention not only to the marking of product compliance with GOST 31173-2003, but also to the presence of an approved fire certificate. As mentioned above, it fixes the fire resistance class.

What is a fire rating? What are they?

Fire resistance class - an indicator that is assigned to a particular product, depending on the indicators obtained during the test of the combustibility of a metal front door. The main parameter is the period of time during which the door "resisted" the ever-increasing temperature and exposure to an open flame. The following main classes of fire resistance are distinguished:

- Ei 30. The number in the name reflects the number of minutes during which the metal front door will be resistant to fire. This is a standard class, which is sufficient for use in residential and industrial premises, as well as public places.

- Ei 60. An increased fire resistance parameter for an hour indicates a sufficient margin of time during which you can not only wait for rescuers, but also evacuate people from a burning building.

— Ei 90. Metal doors of this class are recommended for use in places of increased fire hazard. This may be the production of the appropriate type, gas stations, workshops, kitchens, fuel and lubricants warehouses and other facilities. An hour and a half is enough for the rescuers to localize and extinguish the fire.

Doors made of metal are installed both in residential and industrial, public buildings. They are durable and reliable, and this is achieved through compliance with the requirements of GOST, which relate to the manufacture and installation of doors. It is this standard that ensures the durability and safety of metal sheets for various purposes.

Standards for the production and installation of metal doors

The manufacture of doors from metal, as well as from other materials, is regulated by established and current standards, namely GOST. This set includes the basic production rules, requirements for parameters and materials, as well as the technology for mounting metal doors. Thanks to this, the structures are reliable, have a long service life and ensure human safety.

Any metal doors must comply with the requirements of GOST

The main document regulating the production of metal doors of various types is GOST 31173–2003. Additionally take into account sanitary norms and rules (SNiP), which are a set of requirements for quality and safety of products. These documents regulate the manufacture of metal doors, and the installation of structures is carried out taking into account additional documentation, namely the technological map developed and submitted by the manufacturer.

Video: design features of metal doors

General provisions of GOST for metal doors

GOST 31173–2003 is used for metal door blocks equipped with locking devices and used in buildings and structures of various types. However, the document does not apply to special-purpose products, for example, bulletproof or fire-resistant options, as well as explosion-proof models.

Doors that comply with GOST are reliable protection premises

The standard assumes the classification of metal sheets according to the following criteria:

• purpose, namely external or internal systems;
• the design can have a U-shaped box or with closed loop, as well as with a threshold;
• the system can be from one sash, two identical or different canvases, with opening to the outside or inside the room;
• the number of circuits providing sealing - one or two;
• the finishing of the canvas can be in the form of a painted surface, lining with leather and insulation, lining with glass, wood or wood-tile structures;
• sound insulation level - 1st class (up to 32 dB), 2nd class (26–31 dB) and 3rd class (20–25 dB);
• degree of protection: ordinary, reinforced and protective doors. In each case, there are locks of the appropriate level of strength.

The regulatory document takes into account all the features of metal door systems. For example, seams and joints of metal parts must be carried out by welding. The box can be made of a curved profile, but the thickness of this element must be from 1.5 mm. And also for the door frame, a rectangular profile box is appropriate, and its minimum section is 40x50 mm.

The box is an integral part of the door system

GOST includes not only mandatory requirements to the manufacture of metal doors, but also recommendations that allow you to create reliable products. For example, the standard recommends the use of horizontal and metal reinforcement profiles in the door structure. They are called mullions and make the canvas durable, resistant to mechanical stress.

Can be used inside the sash whole leaf made of steel, which is an additional reinforcement of the door. An acceptable option is also a plate consisting of elements welded together. In this case, the welding seam passes along the reinforcement profiles, which ensures the strength of the final product. The inner additional sheet may be in the form of fibreboard or other solid sheet-type materials. These components of the door are used in the manufacture of paintings different kind, for example, input or insulated.

Insulated doors according to GOST

The design of insulated doors implies maximum protection of the room from heat loss through the door leaf and prevention of cold penetration through cracks. Such doors have in their structure a heat-insulating material, which is located between the outer and inner skin.

Insulated doors are often external

The standard assumes the following features for the manufacture and installation of insulated doors:

• thermal insulation is provided by at least two sealing circuits located along the perimeter of the entire porch;
• all materials used for the manufacture of the canvas and the box must have a sanitary certificate on the safety of the structure;
• paintwork compositions must have high adhesion to the surface of the metal door, and the finish should not peel off, creating gaps and contributing to heat loss;
• if the finish is made of wood or chipboard, then such surfaces should not have cracks that could cause the canvas to blow;
• insulated door models, like any others, are mounted only in a prepared opening with smooth edges;
• during installation, all the gaps between the box and the wall are treated with mounting foam and other structures that eliminate gaps;
• materials used to create a mounting seam must be durable, safe, durable, not subject to decay.

Requirements for the production and installation of insulated systems require the creation of sealed seams and joints. This eliminates the possibility of heat loss from the room.

Steel fire doors

The production of steel fire doors is regulated by GOST R 57327–2016, which includes the basic requirements for this type of structure. This document applies to single- or double-leaf metal doors with glass up to 25% or without it, which are fixed as fire barriers and have appropriate protective properties.

Fire-fighting fabrics are characterized by resistance to fire and tightness

The fire resistance of systems is characterized by such indicators as E - loss of integrity of the web when exposed to heat, I - loss of heat-insulating qualities, S - loss of smoke and gas impermeability resulting from the action of fire. The flame resistance limit can be from 15 to 60 minutes.

The main GOST requirements for these structures, their production and installation are expressed as follows:

• fire-fighting finished products withstand the number of openings / closings of at least 200,000;
• fire doors are always equipped with door closers. For double-leaf structures, devices are also needed to control the sequential closing of the canvases;
• a door with a closer, opened at 90°, must close tightly in less than 5 s. The opening of the web can be carried out with a force of not more than 100 N;
• smoke and gas tight systems always have a closed type box and a threshold. If the canvas is located in the path of movement of people with disabilities, then the threshold should not be present;
• polymer gaskets are used for sealing, between which a gap is not allowed. Thermally expandable gasket options prevent the spread of smoke and carbon dioxide;
• installation involves the use of non-flammable sealants. Latches, locks and other structural elements are always made from fire-resistant structures, which is also relevant for filling canvases. If there is glass, then it is necessarily fire-resistant;
• the service life of the finished structure is at least 10 years. At the same time, the product should not sag, which is achieved by proper installation and careful preparation opening.

Fire doors can have either one or two wings.

Fire-fighting canvases can be supplemented with attachments, for example, video cameras, negotiation elements. In this case, tests to determine their level of resistance to fire are not required. It is worth considering that there can be no sharp, strongly protruding parts in the fittings.

External doors made of steel according to GOST

Metal sheets are a popular option as entry doors. Such products are durable, resistant to climatic influences and other external factors. Their manufacture is carried out in accordance with GOST 31173-2003, which includes the basic requirements for quality, production and installation.

External doors should be as strong and durable as possible.

According to the standard, the system can have fixed inserts of horizontal or vertical type. The maximum weight of moving canvases should not exceed 200 kg.

Entrance systems are resistant to temperature extremes and other climatic influences

Outdoor structures of a burglary or conventional type are often equipped with reinforced elements that prevent illegal opening of the door. The requirements for such details, the manufacture of canvases and their installation are expressed as follows:

• anti-removable crossbars are recommended to be mounted on the side of the leaf where the hinges are located. The pins are fixed by welding or pressing, and their number is determined working documentation, door type;
• the box is equipped with "ears" on both sides. These parts serve to securely fasten the canvas in the opening. "Ears" are fixed to the box by welding;
• the inner filling of the canvas is a sound and thermal insulation materials, which are placed tightly in the frame, excluding the formation of voids;
• the minimum level of sound insulation is 20 dB. This is ensured by the use of modern, high-quality and high-tech materials;
• welds must be made smooth, without cracks and surface scaly. Uneven seams, the presence of welding or burns are not allowed;
• during installation, the quality of work is checked by a construction hydraulic level.

External doors protect the premises from cold, noise, and unauthorized access. Therefore, they must be of high quality, and security must be ensured by the presence of anti-burglary devices, for example, vertical crossbars.

Metal doors with glass

The current standard implies certain requirements for the dimensions of metal door systems. This is due to the fact that the products must have an optimal ratio of size and weight, necessary for comfortable operation and durability of the door.

Doors are diverse not only externally, but also in size.

In the manufacture, the following GOST standards regarding product parameters are taken into account:

• sash diagonals with an area of ​​​​1 m 2 should have lengths with a difference of no more than 2 mm. If the web area is larger, then the length difference cannot be more than 3 mm;
• the edges of the canvas and frame are straight, and the deviation from this cannot be more than 1 mm per 1 m of length;
• the box is fastened with anchor bolts, the cross section of which is at least 10 mm;
• the area of ​​external or other metal doors does not exceed 9 m 2 . In this case, the recommended leaf height is 2200 mm, and the width is up to 1200 mm.

hardware requirements

In the manufacture of metal doors are equipped with locking devices that meet the requirements of standards 5089 and 538. All hinges, locks, crossbars and other parts are made of durable and refractory metal.
