Organization: SAE
Publication Date: 1 July 2017
Status: active
Page Count: 15
scope:

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

c. Initial characterization

LOT RELEASE-Measure of lot-to-lot consistency. 

CERTIFICATION-Periodic check inspection against a specification. 

INITIAL CHARACTERIZATION-Define general characteristics for application development.

It is important to distinguish the usefulness of the individual test methods to assure consistent quality without expending unnecessary resources. 

This document allows for use of recycled, reconstituted, and/or recycled-regrind materials provided that the thermoplastic material:

a. Has not been altered or modified to change its suitability for safe processing or the material's general characteristics,

b. Meets the requirements of its intended use and is identified as such.

Purpose-The purpose of this document is to define the test methods used to characterize thermoplastic materials for the development of automotive specifications.
