1 Scope
This standard specifies the grade of rhodium for the manufacture of flat products, wire, technical products used in instrumentation and other industries.
2 Normative references
This standard uses the regulatory references to the following international standards:
GOST 12227.0−76 Rhodium. Method of spectral analysis
GOST 22864−83 precious metals and their alloys. General requirements for methods of analysis
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 document is replaced (modified), then the use of this standard should be guided by the replaced (modified) document. If the reference document is cancelled without replacement, then the situation in which the given link applies to the extent that does not affect this link.
3 Refer
In the standard made the following designation: Rd — rhodium.
