Standard Test Method for Extrudability, After Package Aging, of Latex Sealants 乳胶密封剂包装老化后可挤压性的标准试验方法
发布日期: 2022-01-01
1.1 本试验方法涵盖了冻融和热循环后测定乳胶密封剂挤出性的实验室程序。 1.2 以国际单位制表示的数值应视为标准值。国际单位制后括号中给出的值仅供参考,不被视为标准值。 1.3 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。 注1: 目前没有类似于该试验方法的ISO标准。 1.4 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====== 5.1 乳胶密封剂的挤出性测量仅表明其易于应用;它们不能预测安装后化合物的性能。 5.2 该试验方法还测量了此类密封剂的冻融稳定性和热稳定性。
1.1 This test method covers a laboratory procedure for the determination of extrudability of latex sealants after freeze-thaw and heat cycling. 1.2 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. 1.3 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. Note 1: Currently there is no ISO standard similar to this test method. 1.4 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 Extrudability measurements of latex sealants serve to indicate only their ease of application; they do not predict the performance capability of the compound after installation. 5.2 This test method also measures freeze-thaw and heat stability of such sealants.
