This SAE Recommended Practice provides a screening procedure for evaluating the susceptibility of plastics to environmental stress cracking by testing their resistance to pure solvents or their mixtures. This method can be used to evaluate effect of complex chemical mixtures with unknown or suspect components, which may be encountered in the polymer's environment.

This recommended practice provides a screening procedure for evaluating the susceptibility of plastics to environmental stress cracking by testing their resistance to pure solvents. This method can then be used to evaluate complex chemical mixtures with components identified as suspect, which are expected to be present in the polymer's environment. It is recommended that ASTM D 543, Resistance of Plastics to Chemical Reagents, also be conducted. This test evaluates chemical effects that cause changes in polymer weight, dimension, appearance or strength.

This SAE Recommended Practice provides a screening procedure for evaluating the susceptibility of plastics to environmental stress cracking by testing their resistance to pure solvents or their mixtures. This method can be used to evaluate effect of complex chemical mixtures with unknown or suspect components, which may be encountered in the polymer's environment. The list of chemicals in Appendix A is intended only to serve as a guide and does not exclude any chemical that may represent the environment the polymer is subjected to in a specific application. As specific environment and exposure conditions are application dependent and could vary significantly from one application to another, the user of the document is recommended to choose the appropriate solvents relevant to the actual application enviroment and is not under any obligation to test the effect of all the chemicals listed in Appendix A.

This SAE Recommended Practice provides a system for classification and specification for limited number of polyamides (nylons) used in the Automotive Industry. Based upon ASTM D 4066, it calls for additional descriptive characteristics and properties commonly used in the Automotive Industry. Recycled polyamides meeting requirements of this practice may be used interchangeably with virgin resins.
