1.1 该试验方法涵盖了对所有类型隔热材料中存在的气味的存在、性质和程度进行主观测定的实验室程序。该测试方法并非旨在评估任何此类气味可能存在的空气质量方面。 1.2 根据该试验方法评估的材料的标准试验条件为149±1.8°F（65±1°C）。参考该试验方法的标准规范可能需要其他试验条件。 1.3 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.4 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。 1.5 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====== 4.1 产生不良气味的隔热材料可能会给占用用这种材料隔热的结构的人带来不适。因此，需要进行检查以确定特定绝缘材料的潜在气味。

1.1 This test method covers a laboratory procedure for subjective determination of the existence, nature, and degree of odors present in all types of thermal insulation materials. This test method is not intended to evaluate the air quality aspects that any such odors may present. 1.2 The standard test condition for material evaluated under this test method is 149 ± 1.8°F (65 ± 1°C). Standard specifications referencing this test method may require other test conditions. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 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. 1.5 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 Thermal insulating materials that produce objectionable odors could cause discomfort to persons occupying a structure insulated with such materials. Therefore, an examination to determine the odor potential of a particular insulation is desirable.
