1.1 本实践旨在确定在标准化夹具中测量的气溶胶泡沫密封剂的空气泄漏率。本实施例提供了制备试验设备的程序，并进一步描述了在进行试验方法之前将气溶胶泡沫密封剂和其他接缝填料应用于设备 E283 . 1.2 本规范允许测试实验室使用测试方法量化气溶胶泡沫密封剂或接缝填充产品的空气泄漏率 E283 并以L/(s·m)报告数据 2 ）根据实践 E29 . 1.3 本规程与试验方法一起使用 E283 虽然测试方法 E283 是用于开窗产品的实验室测试方法，有兴趣对已安装单元进行现场空气泄漏测试的个人应参考测试方法 E783 和AAMA 502。 1.4 气溶胶泡沫密封剂用于各种最终用途，通常旨在减少建筑围护结构中的空气泄漏。 1.5 绝缘材料也适用于本实践的评估。 1.6 没有其他已知的实践或测试方法规定用于确定间隙填充密封剂、干预成型泡沫或绝缘体的空气泄漏率的组件的制备。 1.7 以SI单位表示的值将被视为标准值。SI单位后括号中给出的值仅供参考，不被视为标准值。 1.8 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。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法规限制的适用性。1.9 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 本实践旨在测量通过用于填充建筑施工中发现的接缝的材料的空气流量。 5.2 本实践并不旨在建立选择空气屏障组件的所有所需标准。因此，结果仅用于比较目的，不应被视为等同于现场安装的建筑系统。

1.1 This practice is intended to determine the air leakage rate of aerosol foam sealants as measured in a standardized jig. This practice provides a procedure for preparing the test apparatus and further describes the application of aerosol foam sealant and other joint fillers to the apparatus prior to conducting Test Method E283 . 1.2 This practice allows testing laboratories to quantify the air leakage rate of aerosol foam sealants or joint filling products using Test Method E283 and reporting the data in L/(s · m 2 ) according to Practice E29 . 1.3 This practice is used in conjunction with Test Method E283 . Although Test Method E283 is a laboratory test method used with fenestration products, individuals interested in performing field air leakage tests on installed units should reference Test Method E783 and AAMA 502. 1.4 Aerosol foam sealants are used for a variety of end use applications generally intended to reduce air leakage in the building envelope. 1.5 Insulating type materials also will be found suitable for evaluation with this practice. 1.6 There are no other known practices or test methods that specify the preparation of the assemblies used to determine the air leakage rate of gap filling sealants, dry preformed foams or insulations. 1.7 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 1.8 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. 1.9 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 practice is intended to measure air flow through materials used to fill joints found in building construction. 5.2 This practice does not purport to establish all required criteria for the selection of an air barrier assembly. Therefore, the results should be used only for comparison purposes and should not be seen as the equivalent to field installed building systems.
