1.1 本试验方法涵盖以预成型形状制造的多孔弹性化合物，如垫片，用作玻璃装配用压缩密封件，以及用作建筑施工部门内其他应用中的密封材料。 1.2 以国际单位制表示的数值应视为标准。括号中以美国惯用单位给出的值仅供参考。 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和健康实践，并确定监管限制的适用性。 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====== 4.1 本试验方法量化了多孔弹性垫圈和密封材料的吸水特性。这是一种测试，使说明符能够在材料选择中进行工程判断。

1.1 This test method covers cellular elastomeric compounds that are manufactured in preformed shapes such as gaskets, to be used as compression seals for glazing purposes and as sealing materials in other applications within the building construction sector. 1.2 The values stated in SI units are to be regarded as the standard. The values given in U.S. customary units in parentheses are provided for information purposes only. 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 and health practices and determine the applicability of regulatory limitations prior to use. 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 ====== 4.1 This test method quantifies the water absorption characteristics of cellular elastomeric gaskets and sealing materials. It is a test that enables the specifier to exercise engineering judgment in the selection of materials.
