Summary

1.1 This specification covers compression molding, thermosetting, melamine-formaldehyde molding compounds as further defined in 4.1, resin binder, with or without other resins, intimately combined with fillers, pigments, and any chemical agents needed.

1.2 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 types of molding compounds covered. There may be other requirements necessary to identify particular characteristics. These will be added to the specification as their inclusion becomes generally desirable and the necessary test data and methods become available. Transfer or injection molding will usually result in different physical and electrical characteristics than compression molding.

Note 2—ISO 2122-1977(E) is similar but not equivalent to this specification. Product classification and characterization are not equivalent.

Rationale:

This specification covers compression molding, thermosetting, melamine-formaldehyde molding compounds, resin binder, with or without other resins, intimately combined with fillers, pigments, and any chemical agents needed. The molding compounds shall conform to the requirements specified. Tests shall be performed to determine the properties of the material in accordance with the following test methods: bulk factor; specific gravity; water absorption; impact resistance; flexural strength; deflection temperature; dielectric strength; permittivity and dissipation factor; arc resistance; shrinkage; and comparative tracking index.
