ASTM D5676-99

Standard Specification for Recycled Polystyrene Molding and Extrusion Materials (Withdrawn 2004)

SCOPE
1.1 This specification covers only recycled post-consumer, or post-consumer or industrial/virgin blended polystyrene materials, both crystal and rubber modified, suitable for molding and extrusion.  
1.2 This specification is intended as a means of calling out recycled plastic materials used in the fabrication of end items or parts. Material selection should be made by those having expertise in the plastics field after careful consideration of the design and performance required of the part, environment to which it will be exposed, fabrication process to be used, inherent properties to the material other than those covered by this specification, and economics.  
1.3 The properties included in this specification are those required for identifying the compositions covered. Other requirements necessary for identifying particular characteristics important to specialized applications can be called out using the suffixes as given in Section 5.  
1.4 The values stated in SI units are to be regarded as the standard.  Note 1-There is no equivalent ISO standard.
