GMW GMW14650 PDF

Purpose. This standard covers the performance requirements of plastic parts used in exterior automotive applications. The parts may be functional assemblies or they may be a subassembly of, or attached to, metallic, decorative or functional parts.

Note: For coated (painted, etc.) parts, not all tests are required. See Appendix A, Table A1 for the specific requirements. Additional requirements for coated or painted plastic parts, or parts which incorporated metals in their construction, are given in the relevant performance requirements.

Note: Some paragraphs reference both GM Worldwide (GMW) test procedures and local (Regional) test procedures. As soon as the GMW is available, it supercedes the local test procedure. 

Applicability. All exterior plastic parts that are molded-in-color, painted or hard coated.
