1.1 本试验方法包括测定油漆、清漆、清漆和相关产品中使用的挥发性溶剂和化学中间体中的水。 1.2 本试验方法不适用于存在硫醇、过氧化物或大量醛或胺的情况。 1.3 为了使用本试验方法确定观察值或计算值是否符合相关规范，应根据四舍五入原则，将用于表示规范限值的最后一个右手数字中的试验结果四舍五入到“最接近的单位”- 非实践方法 E29年 . 1.4 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.5 有关危险信息和指南，请参阅供应商的材料安全数据表。 1.6 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。 1.7 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 挥发性溶剂用于各种可能受水影响的化学过程。因此，本试验方法提供了一种用于评估是否符合规范的试验程序。

1.1 This test method covers the determination of water in volatile solvents and chemical intermediates used in paint, varnish, lacquer, and related products. 1.2 This test method is not applicable in the presence of mercaptans, peroxides, or appreciable quantities of aldehydes or amines. 1.3 For purposes of determining conformance of an observed or a calculated value using this test method to relevant specifications, test result(s) shall be rounded off “to the nearest unit” in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E29 . 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 For hazard information and guidance, see the supplier’s Material Safety Data sheet. 1.6 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. 1.7 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 Volatile solvents are used in a variety of chemical processes which may be affected by water. Therefore, this test method provides a test procedure for assessing compliance with a specification.
