1.1 本试验方法包括测量在空气中暴露于高温时固化的电气绝缘清漆的重量损失。 1.2 以国际单位制表示的数值是标准值。 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在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 有关具体预防说明，请参阅第节 7. . 注1: IEC 60216第2部分在技术上等同于本标准。 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====== 5.1 体重减轻有助于表明: 5.1.1 在空气中温度升高时的一种降解形式，以及 5.1.2 可能影响其他成分的挥发物的演变。

1.1 This test method covers the measurement of the loss in weight of cured electrical insulating varnishes on exposure to elevated temperature in air. 1.2 The values stated in SI units are 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 establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific precaution statements, see Section 7 . Note 1: IEC 60216 Part 2 is technically equivalent to this standard. 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 ====== 5.1 Weight loss is useful for indicating: 5.1.1 A form of degradation at elevated temperatures in air, and 5.1.2 Evolution of volatiles that have the potential to affect other components.
