This SAE Recommended Practice is intended to establish uniform procedures for developing specifications for automotive thermoplastics. It is intended for use by automotive companies and their suppliers of molded and/or fabricated parts from thermoplastic materials.

This document lists those test methods and procedures that are useful for the development of specifications for automotive thermoplastic materials. Not all tests are applicable to all thermoplastic materials. Appendix A contains a cross-reference of appropriate test methods for each family of thermoplastic material. The test methods may change (be added or deleted) in future revisions.

This document categorizes the test methods and procedures for developing specifications for automotive thermoplastic materials by categories: a. lot release; b. certification; and c. initial characterization.
