1.1 本试验方法包括测定电气设备用分流器和精密电阻器所用片材的电阻随温度的变化。它适用于通常在0至80°C温度范围内使用的材料。 1.2 以英寸-磅为单位的数值应视为标准值。英寸-磅单位的公制等价物可能是近似值。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任熟悉所有危险，包括制造商提供的本产品/材料的适当安全数据表（SDS）中确定的危险，建立适当的安全、健康和环境实践，并在使用前确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 3.1 本试验方法包括测定由片状材料制成的精密电阻器和分流器的电阻随温度的变化。 3.2 通常在0至80°C温度范围内使用的材料可使用本试验方法进行试验。

1.1 This test method covers the determination of the change of resistance with temperature of sheet materials used for shunts and precision resistors for electrical apparatus. It is applicable to materials normally used in the temperature range of from 0 to 80°C. 1.2 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of inch-pound units may be approximate. 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. ====== Significance And Use ====== 3.1 This test method covers the determination of the change of resistance with temperature for precision resistors and shunts made from sheet materials. 3.2 Materials normally used in the temperature range from 0 to 80°C may be tested using this test method.
