This specification covers electrical contact components made from silver-nickel by powder metallurgical procedures. This covers compositions within the silver-nickel system normally specified by users of electrical contacts. Chemical analysis shall be performed to evaluate material conformance to specified composition requirements. A representative sample of chips may be obtained by milling, drilling, or crushing with dry tools, (without lubrication). In order to obtain free chips, the parts selected for testing shall have the oil extracted, if necessary. Physical tests including microstructure shall be performed on a representative number of specimens.
