介绍
国际标准化组织 (国际标准化组织) 是一个由国家标准机构组成的全球联盟 (ISO成员机构). 国际标准的制定通常通过ISO技术委员会进行. 每个对已成立技术委员会的主题感兴趣的成员团体都有权在委员会中派代表参加. 国际组织, 与ISO有联系的政府和非政府组织也参与了这项工作. ISO 与国际电工委员会密切合作 (国际电工委员会) 关于电气标准化的所有问题.

国际标准是按照第 2 部分给出的规则起草的。 2 ISO/IEC 指令的.

技术委员会的主要任务是制定国际标准. 技术委员会通过的国际标准草案将分发给各成员机构进行投票. 作为国际标准的出版需要至少获得投票批准 75% 成员机构的.

介绍
The purpose of this international standard is to outline the ISO test methods used to characterize epoxy resins. Appropriate and necessary test methods for the characterization of epoxy resins prior to polymerization are listed, along with a brief description of the principles involved.

国际标准化组织 18280-2010 “塑料环氧树脂测试方法”

Due to the particularity of thermosetting resins such as epoxy resins, the performance of pre-crosslinking (useful characteristics for processing) and post-crosslinking (inherent characteristics) is different. 国际标准化组织 3673-2 gives a procedure for determining the inherent properties of crosslinked (or cured) epoxy resins.

1 适用范围
Epoxy resins are a class of synthetic resins that include products ranging from viscous liquids to high melting point solids. Resin molecules contain one or more ethylene oxide or epoxy groups as reaction sites, usually in the form of glycidyl. The commercially important resin is the glycidyl ether of bisphenol A, made from the condensation of epichlorohydrin and diphenylpropane (bisphenol A). Epoxy resins with different properties can also be commercially produced by reacting epichlorohydrin with other materials. In order to be used, the resin needs to be cross-linked with a hardener or hardener. The choice of curing agent is very important in designing an epoxy resin system for a given application. The main reactive groups in the resin, the epoxy and hydroxyl groups, react with many other groups, so a variety of chemicals can be used as curing agents. These include anhydrides, aliphatic and aromatic amines, and polyamides. Some curing agents cross-link the resin at ambient temperatures, while others require heat.

This international standard Outlines ISO test methods for characterizing epoxy resins. The listed attributes to be determined in any given case depend on the agreement between the supplier and the customer.
