1.1 本规范描述了用于建筑施工的单组分溶剂释放密封剂的性能。这些密封剂的配方通常能够承受7.5的最大接缝移动 % 在扩展和7.5中 % 标称接缝宽度的压缩。 1.2 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.3 具有本规范管辖权的委员会不知道ISO或任何其他组织内有任何类似规范。 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====== 6.1 本规范描述了用于建筑施工中一般填缝和密封操作的溶剂释放密封剂。 然而，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，并且并不意味着密封剂在所有物理性质上都是等效的。 6.2 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 describes the properties of a one-component solvent release sealant for use in building construction. These sealants are generally formulated to withstand a maximum joint movement of 7.5 % in extension and 7.5 % in compression of the nominal joint width. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 The committee with jurisdiction of this specification is not aware of any similar specification within ISO or any other organization. 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 ====== 6.1 This specification describes solvent release sealants for general caulking and sealing operations in building construction. However, it should be recognized by the user that not all sealants meeting this specification are suitable for all applications and all substrates and that there is no implication that the sealants are equivalent in all physical properties. 6.2 Refer to Guide C1193 for information on the proper use of sealants meeting this specification.
