1.1 这些测试方法确定了在测试温度下，当挥发性溶剂被赶走时，清漆的非挥发性部分。这有时是对清漆中成膜物质的近似测量。 1.2 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 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）。本标准的使用者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。 有关具体说明，请参阅第节 3. 。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 2.1 这些测试方法适用于清漆，对生产商和用户测定非挥发性含量有用，有时也是清漆中成膜物质的适当测量方法。

1.1 These test methods determine the fraction of a varnish that is nonvolatile at the temperature of the test while volatile solvents are driven off. It is sometimes an approximate measure of the film-forming matter in a varnish. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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 a specific statement, see Section 3 . 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 ====== 2.1 These test methods are applicable to varnish and are useful to producers and users in determining nonvolatile content and are sometimes an appropriate measure of the film-forming matter in varnish.
