2、A number 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 th
3、ermosetting molding compounds. It provides for their identification,quality control, and purchase in such a manner that the purchaser and the seller can agree on the substantial similarity of differentcommercial lots or shipments.1.2 The compounds covered under this specification consist of mixtures
4、 or blends of epoxy resins and curing agents intimatelycombined, in an unreacted or partially reacted condition, with fillers, reinforcements, colorants, and other chemical agents.1.3 The values stated in SI units are to be regarded as the standard.NOTE 1The properties included in this specification
5、 are those required to identify the kinds of molding compounds covered. There may be otherrequirements necessary to define particular characteristics. These will be added to the specification as their inclusion becomes generally desirable and thenecessary test data and methods become available.NOTE

United States14. Classification4.1 GradesThis specification is subdivided into vario
16、us grades of epoxy molding compounds based on physical properties.This specification provides for a system of characterization and identification which enables coverage for all commerciallyavailable grades having properties within the range of the possible combinations as may be selected from Table
17、1. A grade isdesignated by the cell numbers for each property in the order in which they are listed in Table 1. When a property is not specified,a “0” is entered as the cell number.4.2 ClassesEach of the grades of epoxy molding compound may be further subdivided into classes according to specialrequ
18、irements. A class is designated by a capital letter followed by cell designation corresponding to the requirements detailed inTable 2. Where no special requirements, in addition to grade properties, are needed, no class designation is shown.NOTE 3An example of this classification system would be gra

20、sible combination of the properties exists or can be obtained commercially.5. General Requirements5.1 The molding compounds shall be of uniform composition and so formulated as to conform to the requirements of thisspecification.5.2 The apparent density, bulk factor, flow, particle size, and color o
21、f the compounds shall be as agreed upon between thepurchaser and the seller in the order or contract.
