Organization: ASTM
Publication Date: 1 September 2015
Status: active
Page Count: 5
ICS Code (Thermosetting materials): 83.080.10
scope:

This classification system covers polystyrene materials, both crystal and rubber modified, suitable for molding and extrusion.

This classification system and subsequent line callout (specification) are intended to be a means of calling out plastic materials used in the fabrication of end items or parts. It is not intended for the selection of materials. Material selection can be made by those having expertise in the plastics field 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 specification, and the economics.

The properties included in this specification are those required to identify the compositions covered. Other requirements necessary to identify particular characteristics important to specialized applications are to be specified using the suffixes as given in Section 5.

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

NOTE 1-This standard combines elements from ISO 1622-1-2 and ISO 2897-1-2, but is not equivalent to either ISO standard.
