【国外标准】 Standard Specification for Gold-Silver-Platinum Electrical Contact Alloy

This specification covers 69% gold, 25% silver, 6% platinum alloy tubing, rod, wire, and sheet material for sliding electrical contacts. The material shall be finished by such operations (cold working, annealing, turning, grinding, pickling) as are required to produce the prescribed properties. The material shall be tested and conform to chemical composition, and mechanical and electrical property requirements. The mechanical requirements of the material are ultimate tensile strength, elongation, microhardness, hardness, or a combination of these mechanical properties as temper criterion. All tests shall be conducted at room temperature.1.1 This specification covers 69 % gold, 25 % silver, 6 % platinum alloy tubing, rod, wire, and sheet material for sliding electrical contacts.1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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, health, and environmental practices, and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
