1.1 本规范涵盖建筑施工中用于密封接缝的单组分乳胶密封剂。 1.2 制造商应将符合本规范要求的密封剂分类为第节规定的类型和等级之一 4. . 1.3 以国际单位制表示的数值应视为标准。括号中的英寸-磅仅供参考。 1.4 以下预防性警告仅适用于试验方法部分第节 10 ，本规范: 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。 注1: 目前，没有类似于本规范的ISO标准。 ====意义和用途====== 8.1 本规范涵盖第节所述的两种类型和三个等级的乳胶密封剂 4. 为建筑施工中的一般嵌缝和密封操作制定。用户应认识到，并非所有符合本规范的密封剂都适用于所有应用和所有基材。因此，为正确描述密封剂，必须指定类型和等级。试验方法涉及玻璃、木材和铝的特殊标准基材。如果需要使用标准以外的基质进行测试，则应指定用于测试。 8.2 请参阅指南 C1193 有关正确使用符合本规范的密封剂的信息。

1.1 This specification covers one component latex sealants used for sealing joints in building construction. 1.2 A sealant meeting the requirements of this specification shall be classified by the manufacturer to be one of the types and grades defined in Section 4 . 1.3 The values stated in SI units are to be regarded as the standard. The inch-pound in parenthesis are provided for information purposes only. 1.4 The following precautionary caveat pertains only to the test method portion, Section 10 , of this Specification: 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. Note 1: Currently, there is no ISO standard similar to this specification. ====== Significance And Use ====== 8.1 This specification covers two types and three grades of latex sealants as described in Section 4 that are formulated for general caulking and sealing operations in building construction. It should be recognized by the user that not all sealants meeting this specification are suitable for all applications and all substrates. It is essential, therefore, that the type and grade be specified for proper description of a sealant. Test methods relate to special standard substrates of glass, wood and aluminum. If tests are required using substrates in addition to or other than standard, they should be so specified for testing. 8.2 Refer to Guide C1193 for information on the proper use of sealants meeting this specification.
