Purpose/Material Description.

This standard includes the performance requirements of plastic parts installed directly in an engine environment, whereby the applied mechanical and thermal loads are typical of those experienced in both light and heavy duty over the road automotive applications. The parts may be functional within themselves, or the parts may be a subassembly of, or attached to, metallic, or non-metallic functional parts.
