ASTM B576-94(2021) 电接触材料的电弧侵蚀试验的标准指南

1.1 This guide covers the major variables which affect the rate of arc erosion of electrical contact materials and serves as a guide in developing more detailed specifications for arcerosion tests. 1.2 Arc erosion testing involves some vaporization of material. It is the responsibility of the user to become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet for the material being tested. 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.
