1.1 本分类涵盖用于但不限于在运输应用中密封和保持金属和非金属部件组件的硅酮粘合剂和密封剂。材料通过其指定的固化系统和机制固化到弹性状态。 注1: 该分类系统可以满足使用硅材料行业的许多需求。根据需要，可对该分类进行修订；因此，应始终使用最新版本。 1.2 该分类旨在作为硅材料分类的一种方法。它不用于工程设计目的。 1.3 本分类的目的不包括压敏或热熔粘合剂。 1.4 在本分类系统的规定与特定方法的参考ASTM标准相冲突的所有情况下，应以后者为准。 1.5 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.6 以下安全危险警告仅适用于测试方法部分第节 7. ，属于此类。 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。 1.7 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====== 4.1 该分类系统的目的是提供一种方法，通过使用标号来充分识别硅酮粘合剂和密封剂。 4.2 该分类系统旨在为未来的硅酮粘合剂和密封剂增加性能值。

1.1 This classification covers silicone adhesives and sealants intended for but not limited to sealing and retaining metallic and nonmetallic component assemblies in transportation applications. The materials cure to an elastomeric state by their specified cure system and mechanism. Note 1: The classification system may serve many of the needs of industries using silicone materials. This classification is subject to revision, as the need requires; therefore, the latest revision should always be used. 1.2 This classification is intended to be a means of classifying silicone materials. It is not intended for engineering design purposes. 1.3 It is not the intent of this classification to include pressure-sensitive or hot-melt adhesives. 1.4 In all cases in which the provisions of this classification system would conflict with the referenced ASTM standard for a particular method, the latter shall take precedence. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 The following safety hazards caveat pertains only to the test methods portion, Section 7 , of this classification. 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. 1.7 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 ====== 4.1 The purpose of this classification system is to provide a method of adequately identifying silicone adhesives and sealants through the use of a line call-out designation. 4.2 This classification system was designed to permit the addition of property values for future silicone adhesives and sealants.
