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中的非挥发性物质。 1.2 以下内容适用于本标准中的所有规定限值；为了确定是否符合本标准，应根据修约实践方法，将观察值或计算值修约到用于表示规范极限的最后一个右手数字中的“最接近的单位” E29年 . 1.3 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。 1.4 有关危险信息和指南，请参阅本试验方法中所列材料的供应商材料安全数据表。 1.5 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。 有关具体的危险说明，请参阅第节 5. . 1.6 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 本试验方法描述了溶剂中残留物质的分析测量，预计为100 % 105时挥发性 °C±5 °C.挥发性溶剂用于制造油漆、清漆、油漆和其他相关产品，任何残留物的存在都可能影响产品质量或工艺效率。该测试方法有助于制造控制和评估是否符合规范。

1.1 This test method covers the determination of the nonvolatile matter in volatile solvents for use in paint, varnish, lacquer, and related products. 1.2 The following applies to all specified limits in this standard; for purposes of determining conformance with this standard, an observed value or a calculated value 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 . 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 For hazard information and guidance, see the supplier’s Material Safety Data Sheet for materials listed in this test method. 1.5 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 hazard statements, see Section 5 . 1.6 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 describes the analytical measurement of residual matter in solvents that are intended to be 100 % volatile at 105 °C ± 5 °C. Volatile solvents are used in the manufacture of paint, varnish, lacquer, and other related products, and the presence of any residue may affect the product quality or efficiency of the process. This test method is useful in manufacturing control and assessing compliance with specifications.
