1.1 本试验方法涵盖了一种实验室筛选程序，用于确定暴露在高温和紫外线下后，液体应用的结构密封胶玻璃密封胶与附件（如干玻璃垫圈、垫片、垫片和定型块）接触时的兼容性。 1.2 该测试方法包括以下三个参数的观测: 1.2.1 密封剂颜色的变化， 1.2.2 密封剂与玻璃的附着力发生变化，以及 1.2.3 密封剂与被测附件的附着力发生变化。 1.3 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。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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，还没有可比的ISO标准。 1.5 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 在结构密封胶嵌装系统中，密封胶起到结构粘合剂的作用，也可以起到主要耐候密封的作用。作为结构粘合剂，粘合剂结合的完整性至关重要。 5.2 暴露后颜色和附着力的变化是可用于确定系统兼容性的两个标准。经验表明，在这种测试方法中导致附着力损失或变色的附件在实际使用中也可能导致这些情况。

1.1 This test method covers a laboratory screening procedure for determining the compatibility of liquid-applied structural sealant glazing sealants when in contact with accessories such as dry glazing gaskets, spacers, shims, and setting blocks after exposure to heat and ultraviolet light. 1.2 This test method includes the observation of three parameters as follows: 1.2.1 Changes in the color of the sealant, 1.2.2 Changes in the adhesion of the sealant to glass, and 1.2.3 Changes in the adhesion of the sealant to the accessory being tested. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 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: At this time, no comparable ISO standard exists. 1.5 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 In structural sealant glazing systems, the sealant functions as the structural adhesive and may also function as the primary weather seal. As the structural adhesive, the integrity of the adhesive bond is critical. 5.2 Changes in color and adhesion after exposure are two of the criteria that can be used to determine the compatibility of the system. Experience has shown that accessories that cause loss of adhesion or discoloration in this test method may also cause these occurrences in actual use.
