1.1 本规范涵盖以液体或固体形式供应的全活性环氧树脂，可用于铸件、涂料、工具、灌封、粘合剂或加固应用。按适当比例添加硬化剂会使这些树脂聚合成不溶性产品。这些产品的性能可以通过添加各种填料、增强剂、填充剂、增塑剂、触变剂等进行改性。所述环氧树脂也可以用作稳定剂和交联剂；它们可以与其他反应产物结合。 1.2 本规范的功能不是提供工程数据或指导买方选择特定最终用途的材料。通常情况下 表1 和 表2 足以表征本规范下的材料，建议常规检查仅限于测试此类性能。 1.3 以国际单位制表示的数值应视为标准值。 注1: 国际标准化组织 3673–1:1980（E）与本规范类似，但不等同。产品分类和特性不一样。 1.4 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。 1.5 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。

1.1 This specification covers totally reactive epoxy resins supplied as liquids or solids which can be used for castings, coatings, tooling, potting, adhesives, or reinforced applications. The addition of hardeners in the proper proportions causes these resins to polymerize into infusible products. The properties of these products can be modified by the addition of various fillers, reinforcements, extenders, plasticizers, thixotropic agents, etc. The epoxy resins described also can be used as stabilizers and cross-linking agents; and they can be combined with other reactive products. 1.2 It is not the function of this specification to provide engineering data or to guide the purchaser in the selection of a material for a specific end use. Ordinarily the properties listed in Table 1 and Table 2 are sufficient to characterize a material under this specification, and it is recommended that routine inspection be limited to testing for such properties. 1.3 The values stated in SI units are to be regarded as standard. Note 1: ISO 3673–1:1980(E) is similar but not equivalent to this specification. Product classification and characterization are not the same. 1.4 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. 1.5 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.
