1.1 本指南涵盖了气溶胶泡沫密封剂（聚氨酯或乳胶型）在使用温度下温度的一般影响。 1.2 本指南旨在评估在特定温度和标准条件下分配或固化的气溶胶泡沫或两者的观察到的产品分配特性和泡沫质量。 1.3 这种泡沫密封剂主要用于减少空气进出建筑围护结构。 1.4 目前有两种主要的泡沫密封胶类型适用于本标准:单组分聚氨酯和乳胶。 1.5 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.6 没有其他已知的专门用于测量气溶胶泡沫密封剂的产品温度范围的测试方法。 1.7 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。 1.8 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====== 5.1 本指南并非旨在测量在所有可能的基材和环境因素下分配和固化产品的精确温度范围，而是为在特定实验室条件下对泡沫密封剂产品进行基准测试提供依据。 5.1.1 本指南中确定的测试报告的数据、观察结果和排名对进行测试的个人和内部实验室标准来说是主观的。因此，不建议对不同实验室进行的测试报告结果进行直接比较。 5.2 鼓励产品用户评估每种应用，并确定其是否适合实际使用。

1.1 This guide covers the general effects of temperature from the aerosol foam sealant (either polyurethane or latex types) under the use temperatures. 1.2 The guide is intended to estimate the observed product dispensing characteristics and foam quality of aerosol foam dispensed or cured, or both, at specific temperatures and standard conditions. 1.3 Such foam sealants are primarily intended to reduce air movement in and out of building enclosures. 1.4 Currently two main foam sealant types are applicable to this standard: single component polyurethane and latex. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 There are no other known test methods specific for measuring the product temperature range for aerosol foam sealant. 1.7 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. 1.8 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 This guide is not intended to measure the precise temperature range for dispensing and curing product under all the possible substrate and environmental factors, but to provide a basis for benchmarking a foam sealant product under specific laboratory conditions. 5.1.1 The data, observations, and rankings reported for tests identified in this guide are subjective to the individuals conducting the tests and internal laboratory standards. Therefore, direct comparison of results reported for testing conducted by different laboratories is not recommended. 5.2 The product user is encouraged to evaluate each application and determine suitability for actual use.
