1 Scope

This standard applies to platinum powder with a mass fraction of platinum not less than 99.8%, designed for the production of alloys, semi-finished products, chemical compounds of platinum and other purposes.

This standard specifies a method for determining loss of mass on ignition of the powder of platinum in the range of a mass fraction of from 0.0020% to 0.050%.

The method is based on determining the mass difference of the sample before and after calcination.

2 Normative references

This standard uses the regulatory references to the following international standards:
