Annotation of standard text ASTM D6339-11(2019) :

This specification covers syndiotactic polystyrene materials including homopolymer, copolymers, blends, and impact modified, suitable for molding and extrusion. The materials are classified as follows: group 01 - homopolymer; group 02 - copolymer; group 03 - flame retardant; group 04 - blends; group 00 - others. These are further classified as class 1 - general purpose; class 2 - impact modified; and class - others. The reinforced and additive materials are as follows: carbon and graphite-reinforced, glass, mineral-reinforced, lubricants, combination of reinforcement, or fillers, or both. Materials shall be tested, test specimens shall be molded by an injection molding process, and the individual grades shall conform to specified values of tensile strength, flexural modulus, tensile modulus, deflection temperature, specific gravity, Izod impact, and ISO Charpy impact, Vicat softening point, melt flow rate.
