Note — When using this standard appropriate to test the effect of reference standards in the information system of General use — on the official website of the Federal Agency for technical regulation and Metrology on the Internet or in the annual information index «National standards» published as on January 1 of the current year, and the editions of the monthly information index «National standards» for the current year. If replaced with a reference standard, which was given an undated reference, then it is recommended to use the current version of this standard, taking into account all enabled in this version modifications. If replaced with a reference standard, which is given a dated reference, it is recommended to use the version of this standard referred to above by year of approval (acceptance). If after approval of this standard in the reference standard, which is given a dated reference, a change affecting a provision to which reference, the provision is recommended to be applied without taking into account this change. If the reference standard is cancelled without replacement, the position in which reference is made to him, recommended to be used in part not affecting this link.
3 Classification
3.1 Profiles divided by state of material:
a) without heat treatment (hot-pressed) — no symbol [1561 (АМг61), 1980 (В48−4), 1985ч, 1941 (K48−2), 1943 (K48−2пч)];
b) annealed — M [1561М (АМг61М)];
C) hardened and naturally aged — T (1985чТ);
d) hardened and artificially aged — T1 [1980Т1 (В48−4Т1), 1941Т1 (K48−2Т1), 1943Т1 (K48−2пчТ1)].
4 Basic parameters and dimensions
4.1 the Shape and dimensions of profiles of square cross-sections, the diameters of the circumscribed circle and the theoretical weight of 1 m length according to GOST 13616, 13617 GOST, GOST 13618, 13619 GOST, GOST 13620, 13621 GOST, GOST 13622, 13623 GOST, GOST 13624, GOST 13737, 13738 GOST, GOST 17575, 17576 GOST, GOST 29296, 29303 GOST, GOST R 50066, 50067 GOST R, GOST R 50077, GOST R 55395, catalogs and drawings, agreed by the manufacturer and the consumer.
