ASTM D6339-11

Standard Classification System for and Basis for Specifications for Syndiotactic Polystyrene Molding and Extrusion (SPS)

ABSTRACT
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.
SCOPE
1.1 This classification system covers syndiotactic polystyrene materials including homopolymer, copolymers, blends, and impact modified, suitable for molding and extrusion. Recycled product will be addressed in a separate standard.
1.2 This classification system and subsequent line callout (specification) are intended to provide a means of calling out plastic materials used in fabrication of end use items or parts. It is not intended for the selection of matierials. Material selection can be made by those having expertise in the plastics field only after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be employed, the inherent properties of the material other than those covered by this classification system, and the economics.
1.3 The properties included in this classification system are those required to identify the compositions covered. Other requirements necessary to identify particular characteristics important to specialized applications are to be called out using the suffixes given in Section 5.
Note 1—There is no known ISO equivalent to this standard.
