Standard Classification System for Specifying Plastic Materials
2020
23
ASTM Vol.08.02 (2022)
This standard provides a classification system for tabulating the properties of unfilled, filled, and reinforced plastic materials suitable for processing into parts. NOTE 1: The classification system serves many of the needs of industries using plastic materials. The standard is subject to revision as the need requires; therefore, the latest revision should always be used. The classification system and subsequent line call-out (specification) is intended to be a means of identifying plastic materials used in the fabrication of end items or parts. It is not intended for the selection of materials. Material selection should 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 not covered in this document, and the economic factors.
