3、October 2004.1. Scope*1.1 This specification covers requirements for epoxy ther-mosetting molding compounds. It provides for their identifica-tion, quality control, and purchase in such a manner that thepurchaser and the seller can agree on the substantial similarityof different commercial lots or s
4、hipments.1.2 The compounds covered under this specification consistof mixtures or blends of epoxy resins and curing agentsintimately combined, in an unreacted or partially reactedcondition, with fillers, reinforcements, colorants, and otherchemical agents.1.3 The values stated in SI units are to be
5、regarded as thestandard.NOTE 1The properties included in this specification are those re-quired to identify the kinds of molding compounds covered. There may beother requirements necessary to define particular characteristics. Thesewill be added to the specification as their inclusion becomes genera
6、llydesirable and the necessary test data and methods become available.NOTE 2There is no similar or equivalent ISO standard.2.
