1.1 本指南提供了一个分类系统，用于将适用于将零件或组件固定在一起的粘合剂的特性制成表格。本指南的使用还提供了制定粘合剂标准规范所需的信息。 注1: 该分类系统可以满足使用粘合剂的行业的许多需求。本指南可根据需要进行修订；因此，应始终使用最新版本。 1.2 限制- 该分类系统旨在作为识别粘合剂的一种方法。它不用于选择材料。材料选择应由在粘合剂领域具有专业知识的人员在仔细考虑零件所需的设计和性能、其将暴露的环境、将采用的附着过程、本文件未涵盖的材料的固有特性和经济因素后进行。 1.3 该分类系统基于这样一个前提，即可以使用基本特性将粘合剂排列成广泛的通用族，将材料分为组、类和等级。 1.4 在所有情况下，如果该分类系统的规定与特定材料的参考ASTM规范相冲突，则应以后者为准。 1.5 以国际单位制表示的数值，详见 IEEE/ASTM SI 10 ，将被视为标准。 ====意义和用途====== 4.1 该分类系统的目的是提供一种识别粘合剂的方法，以便为行业提供一个可普遍用于材料的系统。它进一步提供了一种通过使用使用本指南制定的标准来指定这些材料的方法。 4.2 开发该分类系统是为了允许添加未来的粘合剂。

1.1 This guide provides a classification system for tabulating the properties of adhesives suitable for holding parts or assemblies together. The use of this guide also provides information necessary for the development of standard specifications for adhesives. Note 1: This classification system may serve many of the needs of industries using adhesives. This guide is subject to revision as the need requires; therefore, the latest revision should always be used. 1.2 Limitations— This classification system is intended to be a means of identifying adhesives. It is not intended for the selection of materials. Material selection should be made by those having expertise in the adhesives field after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the attachment process to be employed, the inherent properties of the material not covered in this document, and the economic factors. 1.3 This classification system is based on the premise that adhesives can be arranged into broad generic families using basic properties to arrange the materials into groups, classes, and grades. 1.4 In all cases where the provisions of this classification system would conflict with the referenced ASTM specification for a particular material, the latter shall take precedence. 1.5 The values stated in SI units, as detailed in IEEE/ASTM SI 10 , are to be regarded as the standard. ====== Significance And Use ====== 4.1 The purpose of this classification system is to provide a method of identifying adhesives in order to give industry a system that can be used universally for materials. It further provides a means for specifying these materials by the use of the standards that are developed using this guide. 4.2 This classification system was developed to permit the addition of future adhesives.
