Standard Specification for Molding Compounds, Thermosetting

This specification covers the basic properties of thermoset molding plastic compounds and the test methods used to establish the properties. The plastic compounds shall be a resin, cellulose-filled or mineral/glass-filled phenolic, melamine, polyester, diallyl iso-phthalate, diallyl ortho-phthalate, silicone, or epoxy. Standard test specimens shall be in the as-received condition or shall be conditioned before testing by humidity, immersion, or temperature conditioning. The specimens shall undergo mechanical or physical qualification tests which shall conform to the following properties: compressive strength; dimensional stability; flexural strength; heat deflection temperature; heat resistance; impact strength; tensile strength; and water absorption. Electrical qualification tests shall be conducted; wherein, the specimens shall comply with the following requirements: arc resistance; dielectric breakdown; dielectric constant; dielectric strength; dissipation factor; surface resistance; comparative track index; volume resistance; and water extract conductance. Tests for combustion qualification shall also be performed to determine the flame resistance ignition time, burning time, flammability, and toxicity requirements. Batch acceptance tests shall be conducted as well to ensure the quality conformance of the specimens.
