1.1 本试验方法描述了一种实验室程序，用于测量作为标准基质和/或其他基质的波特兰水泥砂浆上应用的预固化弹性填缝料（以下简称“应用密封”）和（如果未应用，以下简称“密封”）的模量、撕裂度、接缝移动能力和粘附性能。它在干燥、潮湿、冷冻、热老化或人工气候老化条件下或两者兼有后测试这些性能。 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 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 对本标准具有管辖权的委员会不知道其他委员会或组织发布的任何类似标准。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（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 密封件以扁平挤压形状制造，主要用于跨越接头开口。使用液体应用粘合剂将密封件粘附到建筑基材上，以密封建筑开口，例如面板接缝、金属泛水接缝或其他接缝，代替传统液体应用密封剂。在实际使用中，活动接头中应用的密封件的失效通常表现为密封件的内聚失效；粘合剂和基材之间的粘合剂失效；粘合剂和密封件之间的粘合剂失效；基板的内聚破坏或平行于接头长度的撕裂扩展。 图1 标准基板试样组件 图2 斜桥接头配置 图3 万向节配置 图4 在密封件中间切割5 mm用于撕裂扩展测试的试样 图5 部分撕裂 如上图所示，撕裂垂直于关节长度传播，左侧；或以任何角度指向接缝墙，如上图所示，右侧。在每种情况下，撕裂都会在接缝处停止，两侧完整的未断裂接缝长度至少为12.5 mm。 图6 撕裂 撕裂平行于接缝壁传播，并打开一侧或两侧。 5.2 本试验方法可用于测试粘合剂与基材和密封件的附着力、不同应变下的拉伸载荷以及试样暴露于潮湿、寒冷、炎热和人工风化条件后在不同应变下的抗撕裂性。 所有或部分这些属性都是在实际工作现场体验到的。

1.1 This test method describes a laboratory procedure for measuring modulus, tear, joint movement ability and adhesion properties of applied, Precured Elastomeric Joint Sealants, hereinafter referred to as “applied seal” and if not applied, hereinafter referred to as “seal,” on portland cement mortar as a standard substrate and or other substrates. It tests these properties after dry, wet, frozen, heat aged or artificially weather-aged conditionings, or both. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information 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 The committee with jurisdiction over this standard is not aware of any similar standard published by another committee or organization. 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 Seals are manufactured in flat extruded shapes and are primarily used to span joint openings. The seal is adhered to construction substrates utilizing a liquid applied adhesive, to seal building openings such as panel joints, metal flashing joints or other joints in place of conventional liquid applied sealants. In actual use, failure of an applied seal in an active joint is usually manifested by cohesive failure of the seal; adhesive failure between the adhesive and the substrate; adhesive failure between the adhesive and the seal; cohesive failure of the substrate or tear propagation parallel to the joint length. FIG. 1 Standard Substrate Test Specimen Assemblies FIG. 2 Beveled Bridge Joint Configuration FIG. 3 U-joint Configuration FIG. 4 Test Specimen Showing 5 mm Cut in the Middle of the Seal for Tear Propagation Testing FIG. 5 Partial Tear Tear propagates perpendicular to the length of the joint as shown above, left; or at any angle leading to the joint wall as shown above, right. In each case tear stops at the joint wall with an intact unbroken joint length on both sides of at least 12.5 mm. FIG. 6 Tear Tear propagates parallel to the joint wall and opens one side or both sides. 5.2 This test method can be used for testing the adhesion of the adhesive to the substrate and to the seal, tensile load at various strains and tear resistance at various strains after the specimens are exposed to wet, cold, hot and artificial weathering conditionings. All or some of these properties are experienced on actual job sites.
