Introduction date 01.01.71

1. This standard establishes the graphic designations of materials in sections and on facades, as well as the rules for applying them to the drawings of all industries and construction.

(Changed edition, Rev. No. 2).

1a. The general graphic designation of materials in sections, regardless of the type of materials, must correspond to the drawing. one a.

(Introduced additionally, Rev. No. 1).

2. Graphic designations of materials in sections, depending on the type of materials, must correspond to those given in Table. one.

It is allowed to use additional designations of materials not provided for in this standard, explaining them in the drawing.

Material

Designation

1. Metals and hard alloys

2. Non-metallic materials, including fibrous monolithic and slab (pressed), except for those specified below

3. Wood

4. Natural stone

5. Ceramics and silicate masonry materials

7. Glass and other translucent materials

8. Liquids

9. Natural soil

Notes:

1. Composite materials containing metals and non-metal materials are referred to as metals.

2. The graphic designation of paragraph 3 should be used when it is not necessary to indicate the direction of the fibers.

3. The graphic designation of clause 5 should be used to designate brick products (fired and unfired), refractories, building ceramics, electrical porcelain, cinder blocks, etc.

(Changed edition, Rev. No. 1, 2).

3. Establish the following designations of the mesh and backfill of any material (in cross section) indicated in Fig. one.

a - grid; b - backfill

4. When selecting materials and products on the view (facade), their graphic designations must correspond to those indicated in Table. 2.

table 2

Notes:

1. (Deleted, Rev. No. 1).

2. To clarify the type of material, in particular materials with the same type designation, graphic designation should be accompanied by an explanatory inscription on the drawing field.

3. In special building structural drawings for reinforcing reinforced concrete structures, designations according to GOST 21.501.

4. The designation of the material on the view (facade) is allowed to be applied not completely, but only small areas along the contour or spots inside the contour.

5. Inclined parallel hatching lines should be drawn at an angle of 45 ° to the image contour line (Fig. 2a) or to its axis (Fig. 2b), or to the lines of the frame of the drawing (Fig. 2).

If the hatching lines reduced to the drawing frame lines at an angle of 45 ° coincide in direction with the contour lines or axial lines, then instead of the 45 ° angle, an angle of 30 ° or 60 ° should be taken (Fig. 3 and 4).

Hatching lines should be applied with an inclination to the left or right, but as a rule, in the same direction on all sections related to the same part, regardless of the number of sheets on which these sections are located.

(Changed edition, Rev. No. 1).

6. The distance between parallel straight hatching lines (frequency) should, as a rule, be the same for all sections of a given part performed on the same scale and is selected depending on the hatching area and the need to diversify the hatching of adjacent sections. The specified distance should be from 1 to 10 mm, depending on the hatching area and the need to diversify the hatching of adjacent sections.

(Revised edition, Rev. No. 2).

7. Narrow and long cross-sectional areas (for example, stamped, rolled and other similar parts), the width of which in the drawing is from 2 to 4 mm, it is allowed to hatch completely only at the ends and at the contours of the holes, and the rest of the cross-sectional area - in small areas in several places (Fig. 5 and 6). Glass hatching lines (Fig. 7) should be applied with a slope of 15-20 ° to the line of the larger side of the section contour.

(Revised edition, Rev. No. 4).

8. Narrow cross-sectional areas, the width of which in the drawing is less than 2 mm, may be shown blackened, leaving gaps between adjacent sections of at least 0.8 mm (Fig. 8, 9).

In construction drawings, it is allowed to designate any material as metal on sections of a small area or not to use the designation at all, making an explanatory inscription in the field of the drawing.

9. the designation specified in paragraph 3 of the table. 1, and the designation of the filling in the section is performed by hand.

(Changed edition, Rev. No. 1).

10. For adjacent sections of two parts, you should take the slope of the hatching lines for one section to the right, for the other - to the left (opposite hatching).

When hatching "in a cage" for adjacent sections of two parts, the distance between the lines of hatching in each section must be different.

In adjacent sections with hatching of the same slope and direction, you should change the distance between the hatching lines (Fig. 10) or shift these lines in one section relative to another without changing their angle of inclination (Fig. 11).

11. For large cross-sectional areas, as well as when specifying the soil profile, it is allowed to apply the designation only at the contour of the section with a narrow strip of uniform width (Fig. 12).

(Revised edition, Rev. No. 1).
