1.1 本试验方法包括测定电绝缘清漆固化过程中排放的挥发性有机化合物的量。 1.2 以国际单位制表示的数值应视为标准值。括号中给出的值是英寸-磅单位的数学转换，仅供参考，不被视为标准值。 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。 参见第节 7. 具体预防措施。 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====== 4.1 本试验方法测定了电绝缘清漆的挥发性有机物含量。它使用一种程序，在该程序中，烤制含有已知量清漆的盘子，并测量挥发性有机化合物的量。 计算以g/L或lb/gal表示。该试验方法适用于所有类型的清漆。然而，在相同条件下烘烤的水性清漆需要测定含水量，并根据实践进行计算 D3960 . 4.1.1 在电气绝缘清漆的固化过程中，一些有机材料会挥发。测定挥发量有助于估计电气装置上的固化清漆量和制造设施的挥发性有机排放物。

1.1 This test method covers the determination of the amount of volatile organic compounds emitted during cure of electrical insulating varnishes. 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound 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 establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. See Section 7 for specific precautions. 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 ====== 4.1 This test method determines the volatile organic content of an electrical insulating varnish. It utilizes a procedure where dishes containing a known amount of varnish are baked and the amount of volatile organic compound is measured. Calculations are performed to express this in g/L or lb/gal. This test method is applicable to all types of varnishes. However, waterborne varnishes while baked under the same conditions need to have water content determined and calculations performed in accordance with Practice D3960 . 4.1.1 During the cure of electrical insulating varnishes some organic material is volatilized. A determination of the amount that is volatilized is useful for estimating the amount of cured varnish on electrical units and volatile organic emissions from a manufacturing facility.
