Anotace

This specification covers the classification, testing, and requirements of polyphthalamide (PPA) materials, both virgin and recycled, suitable for injection molding. This specification is intended to be a means of calling out plastics materials used in the fabrication of end items or parts, and not for the selection of materials. The materials are classified into groups according to crystallinity, and are further subdivided into classes and grades as specified. Materials shall be sampled, prepared, and conditioned appropriately for testing, for which specimens shall conform to specified values of the following requirements: inherent viscosity; melting temperature; glass transition; tensile strength; flexural strength and modulus; Izod impact strength; deflection temperature; and moisture.
