Abstract
This specification covers electrical contact components made from silver-tungsten carbide by powder metallurgical procedures. This specification covers compositions within the silver-tungsten carbide system. The material shall conform to composition limits. Chemical analysis shall be performed to deteremine material conformance to specified composition requirements. The contact components shall agree on qualification tests for determination of physical properties. The tests shall be performed on production parts wherever practical or applicable. The test shall be determined after consideration of the function of the part.
Scope
1.1 This specification covers electrical contact components made from silver-tungsten carbide by powder metallurgical procedures.
1.2 This specification covers compositions within the silver-tungsten carbide system normally specified by users of contacts.
1.3 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
