Note — When using this standard appropriate to test the effect of reference standards for the sign «National standards» drawn up as of January 1 of the current year and related information signs, published in the current year. If the reference standard is replaced (changed), when using this standard should be guided by replacing (amended) standard. If the reference standard is cancelled without replacement, then the situation in which the given link applies to the extent that does not affect this link.

3 legend

3.1 In the standard, the following symbols grades of palladium and alloys on its basis.

The symbol consists of letters designating components: PD — palladium, And iridium, SR — silver, cobalt, M is copper, followed by digits which indicate the nominal mass fraction of palladium in the component (components) in the alloy. Mass fraction of the last component in a symbol of the brand figures do not indicate if he is ignoble.

4 Technical requirements

4.1 Chemical composition of palladium and alloys on its basis must comply with the requirements of tables 1−3.


Table 1 — Chemical composition of palladium

Percentage

Table 2 — Chemical composition of palladium-iridium alloys

Percentage

Table 3 — Chemical composition of palladium-silver, palladium-silver-cobalt and palladium-silver-copper alloys

Percentage

4.2 Chemical composition determines:

— palladium — GOST 12225;

— alloys based on palladium according to GOST 12550.1, 12550.2 GOST, GOST 12558.1, 12558.2 GOST, GOST 12560.1, 12560.2 GOST, GOST 12561.1, 12561.2 GOST, GOST 22864.

Allowed to determine the chemical composition of alloys other methods of equal accuracy standard.
