2A. Determination of chemical composition of aluminum alloys is carried out according to GOST 11739.7, 11739.11 GOST-GOST 11739.13, GOST 11739.16, 11739.17 GOST, GOST 11739.19, GOST 11739.24.

Allowed to determine the chemical composition of the other methods, accuracy is not inferior to the standard.

The differences in the evaluation of the chemical composition determination is carried out according to GOST 11739.7, 11739.11 GOST-GOST 11739.13, GOST 11739.16, 11739.17 GOST, GOST 11739.19, GOST 11739.24.
