ASTM B684/B684M-16 PDF

Scope: 1.1 This specification covers an 858201;% platinum—158201;% iridium alloy, and a 908201;% platinum—108201;% iridium alloy, in the form of rod, wire, strip, and sheet material for electrical contacts.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.3 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 Safety Data Sheet (SDS) 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.
