1.1 本试验方法包括一个比较程序，用于观察挥发性有机溶剂和稀释剂的特性和残留气味，以确定其在溶剂系统中的气味可接受性。 1.2 本试验方法不用于确定材料之间细微的气味差异或确定气味强度。 1.3 如果液体在室温下蒸发至干燥的时间超过30分钟或按照约定，建议不要使用该试验方法来测定液体的残留气味。 1.4 以国际单位制表示的值应视为标准值。本标准不包括其他测量单位。 1.5 本标准并不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建立适当的安全、健康和环境实践，并确定监管限制的适用性。 有关具体危险说明，请参阅第节 4. . 1.6 有关具体危险信息，请参阅供应商的材料安全数据表（MSDS）。 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 3.1 比较气味特征可与其他测试相结合，用于产品识别和评估是否符合规范。 3.2 残余气味特征可用于判断是否存在可能与制造或分配过程中的污染相关的相对非挥发性材料。由于挥发性溶剂和稀释剂用于多种化学工艺，残留材料可能会影响此类工艺的效率，因此本试验方法为制造控制和评估是否符合规范提供了比较试验。

1.1 This test method covers a comparative procedure for observing the characteristic and residual odors of volatile organic solvents and diluents to determine their odor acceptability in a solvent system. 1.2 It is not intended that this test method be employed to determine subtle odor differences between materials or to determine odor intensity. 1.3 It is recommended that this test method not be employed to determine the residual odor of a liquid if its time for evaporation to dryness at room temperature exceeds 30 min or as agreed upon. 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 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 4 . 1.6 For specific hazard information, see the supplier's Material Safety Data Sheet (MSDS). 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 ====== 3.1 The comparative odor characteristics can be used, combined with other tests, for product identification and assessing compliance with a specification. 3.2 The residual odor characteristics can be used to judge the presence of relatively nonvolatile materials that may be associated with manufacture or contamination during distribution. Since volatile solvents and diluents are used in a wide variety of chemical processes and residual materials may affect the efficiency of such processes, this test method provides a comparative test for manufacturing control and assessing compliance with a specification.
