1.1 本试验方法涵盖了定量测量结构密封胶玻璃应用中使用的中空玻璃边缘密封件的拉伸强度、刚度和粘附性能的实验室程序。这些应用的边缘密封使用结构密封胶将玻璃和边缘垫片粘合到一个整体密封中空玻璃单元中。在典型应用中，结构密封胶在风荷载和重力荷载作用下将外部lite固定到位，并将边缘垫片保持在适当位置。 此后，术语“中空玻璃”将缩写为“IG” 1.2 本试验方法定义的IG二次密封剂特性的表征在很大程度上取决于玻璃和边缘垫片的清洁程序、IG垫片轮廓、垫片的位置和主要IG密封剂的应用。本试验方法的用户必须认识到IG边缘密封组件影响二次密封剂的性能。 1.3 该测试方法确定的值将是所测试的特定边缘密封组件的特征。 注1: 目前，只有专门配制用于IG单元二次密封的弹性、化学固化硅酮密封剂被认为具有在结构密封胶玻璃应用中使用的必要耐久性。 1.4 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。 1.5 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。 1.6 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 IG单元通常用结构密封胶粘附在金属框架系统上。在这种应用中，通常只有玻璃的内部部分粘附在框架上。因此，任何向外作用或负风荷载的很大一部分必须由IG装置两个Lite之间的接缝密封承受张力。本试验不会提供IG装置主密封完整性的信息；然而，它可以提供一次IG蒸汽密封和二次结构密封胶之间的负载共享数据。 5.2 虽然本试验方法规定了一种环境条件，但其他环境条件和暴露周期可用于特定项目评估。报告数据时应说明此类偏差。

1.1 This test method covers a laboratory procedure for quantitatively measuring the tensile strength, stiffness, and adhesion properties of insulating glass edge seals that are used in structural sealant glazing applications. Edge seals for these applications use a structural sealant to bond both glass lites and the edge spacer into a monolithic sealed insulating glass unit. In typical applications, the structural sealant acts to hold the outside lite in place under wind and gravity load and to maintain the edge spacer in its proper position. Hereafter, the term “insulating glass” will be abbreviated as “IG.” 1.2 The characterization of the IG secondary sealant properties, as defined by this test method, are strongly dependent on glass and edge spacer cleaning procedures, IG spacer profile, location of spacer, and primary IG sealant application. Users of this test method must recognize that the IG edge seal assembly influences the secondary sealant properties. 1.3 The values determined by this test method will be characteristic of the particular edge seal assembly that is tested. Note 1: Presently, only elastomeric, chemically curing silicone sealants specifically formulated for use as the secondary seal of IG units are recognized as having the necessary durability for use in structural sealant glazing applications. 1.4 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. 1.5 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. 1.6 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 Frequently IG units are adhered with a structural sealant to a metal framing system. In such applications, only the inward lite of glass is usually adhered to the frame. As a result, a significant portion of any outward-acting or negative wind load must be carried in tension by the joint seal between the two lites of the IG unit. This test will not provide information on the integrity of the IG unit primary seal; however, it may provide data on load sharing between the primary IG vapor seal and the secondary structural sealant. 5.2 Although this test method prescribes one environmental condition, other environmental conditions and exposure cycles can be employed for specific project evaluation. Such deviations should be described when reporting the data.
