1、Designation: D3013 99 (Reapproved 2012)Standard Specification forEpoxy Molding Compounds1This standard is issued under the fixed designation D3013; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number
2、 in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification covers requirements for epoxy ther-moset
3、ting molding compounds. It provides for theiridentification, quality control, and purchase in such a mannerthat the purchaser and the seller can agree on the substantialsimilarity of different commercial lots or shipments.1.2 The compounds covered under this specification consistof mixtures or blend
4、s 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 regarded as thestandard.NOTE 1The properties included in this specification are those r
5、equiredto identify the kinds of molding compounds covered. There may be otherrequirements necessary to define particular characteristics. These will beadded to the specification as their inclusion becomes generally desirableand the necessary test data and methods become available.NOTE 2There is no s

10、ions of terms used in this specifica-tion are in accordance with Terminology D883.4. Classification4.1 GradesThis specification is subdivided into variousgrades of epoxy molding compounds based on physical prop-erties. This specification provides for a system of characteriza-tion and identification
11、which enables coverage for all commer-cially available grades having properties within the range of thepossible combinations as may be selected from Table 1.Agrade is designated by the cell numbers for each property in theorder in which they are listed in Table 1. When a property is notspecified, a
12、“0” is entered as the cell number.4.2 ClassesEach of the grades of epoxy molding com-pound may be further subdivided into classes according tospecial requirements. A class is designated by a capital letterfollowed by cell designation corresponding to the requirementsdetailed in Table 2. Where no spe
13、cial requirements, in additionto grade properties, are needed, no class designation is shown.1This specification is under the jurisdiction of ASTM Committee D20 onPlastics and is the direct responsibility of Subcommittee D20.16 on ThermosettingMaterials.Current edition approved Dec. 1, 2012.
