INTRODUCED by Gosstandart of Russia

2 ADOPTED by the Interstate Council for standardization, Metrology and certification (Protocol No. 12−97, dated 21 November 1997)

The adoption voted:

3 Resolution of the State Committee of the Russian Federation for standardization, Metrology and certification dated April 22, 1998 N 136 inter-state standard GOST 13618−97 introduced directly as state standard of the Russian Federation from January 1, 1999

1 SCOPE

This standard specifies the gauge extruded oblique-angled fitting angle-profile sections of aluminum, aluminum and magnesium alloys manufactured by hot pressing.

2 BASIC PARAMETERS

2.1 profile Numbers and sizes shall be as given in figure 1 and in table 1.

Figure 1

Table 1 — Numbers of profiles, sizes and theoretical mass

2.2 Theoretical weight of 1 m of the profile of the aluminum alloys is calculated based on nominal sizes at a density of 2.85 g/cm, which corresponds to the density of the aluminum alloy V95 brand.

Theoretical weight of 1 m of the profile from magnesium alloys is calculated based on nominal sizes at a density of 1.80 g/cm, which corresponds to the density of the magnesium alloy MA14 brand.

2.3 Conversion factors for calculating the approximate theoretical weight of 1 m of profile aluminium and aluminium alloys is given in table A. 1 of Annex A.

Conversion factors to calculate the approximate theoretical weight of 1 m of profile of magnesium alloys are presented in table B. 1 of Annex B.

2.4 numbers corresponding profiles previously existing designations are given in table B. 1 of Annex B.
