1.1 本试验方法描述了测定建筑施工中使用的单组分和多组分化学固化密封剂流变（流动）特性的实验室程序。 1.2 其它合适的流动特性可以在卖方和买方或指定者之间达成一致。在不需要绝对调平的倾斜接头中，可能需要特殊的非下垂特性和较低的流动特性。 附注1: 密封剂以各种流变特性提供，从可倾倒的流体到坚硬的不下垂的糊状物。多组分密封剂作为基础组分提供，活化剂或固化剂单独包装。混合多个部分后，密封剂就可以应用了。单组分密封剂在打开包装时即可使用，通常取决于外部环境进行固化。1.3 本试验方法描述了四种类型的接缝密封剂: 1.3.1 I型- 单组分可流动或自流平， 1.3.2 II型- 单组分非流挂、 1.3.3 III型- 多组分可流动或自流平，以及 1.3.4 IV型- 多组分非凹陷。 1.4 以SI单位表示的值应被视为标准。括号中给出的值仅供参考。 1.5 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 1.6 本国际标准是根据世界贸易组织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（技术性贸易壁垒）委员会。 ======意义和用途====== 5.1 从该测试方法获得的结果仅仅是单组分或多组分密封剂在两个预定温度下应用于设定的接头配置时水平或垂直流动程度的测量。只有在相同温度下调节的样品可以直接比较。

1.1 This test method describes a laboratory procedure for the determination of rheological (flow) properties of single- and multi-component chemically curing sealants for use in building construction. 1.2 Other suitable flow characteristics may be agreed upon between the seller and purchaser or specifier. Special non-sag properties and lower flow characteristics may be required for use in sloping joints where absolute leveling is not desired. Note 1: The sealants are supplied in various rheological properties ranging from pourable fluids to stiff non-sagging pastes. Multi-component sealants are supplied as a base component with an activator or curing agent separately packaged. After mixing the multiple parts, the sealant is ready for application. Single-component sealants are supplied ready for use upon opening of the package and usually depend on the external environment for cure. 1.3 This test method describes four types of joint sealants: 1.3.1 Type I— Single-component flowable or self-leveling, 1.3.2 Type II— Single-component non-sag, 1.3.3 Type III— Multi-component flowable or self-leveling, and 1.3.4 Type IV— Multi-component non-sag. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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 The results obtained from this test method are simply a measure of the degree of horizontal or vertical flow of single-component or multi-component sealants when applied to a set joint configuration at two pre-determined temperatures. Only samples conditioned at the same temperature may be directly compared.
