ASTM D3013-13

Standard Specification for Epoxy Molding Compounds

ABSTRACT
This specification covers the requirements for epoxy thermosetting molding compounds and provides for their identification, quality control, and purchase. Material covered in this specification consists of mixtures or blends of epoxy resins and curing agents intimately combined with fillers, reinforcements, colorants, and other chemical agents. The epoxy molding compounds are classified into grades based on physical properties, which may be further classified into classes (dielectric or flame retardant) according to special requirements. The molding compounds shall be manufactured with uniform composition and with the apparent density, bulk factor, flow, particle size, and Au: Pls. note that although caption make reference to color online, figures in print will appear in black and white. In conformity with the requirements specified. Tests for water absorption, flexural strength, impact resistance, tensile strength, deflection temperature under load, permittivity and dissipation factor, wet and dry dielectric strength, arc resistance, and flammability shall be performed and shall conform to the requirements specified.
SCOPE
1.1 This specification covers requirements for epoxy thermosetting 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 different commercial lots or shipments.  
1.2 The compounds covered under this specification consist of mixtures or blends of epoxy resins and curing agents intimately combined, 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 1—The properties included in this specification are those required to identify the kinds of molding compounds covered. There may be other requirements necessary to define particular characteristics. These will be added to the specification as their inclusion becomes generally desirable and the necessary test data and methods become available. Note 2—There is no known ISO equivalent to this standard.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
