SAE J322:2003 pdf download Nonmetallic Trim Materials-Test Method for Determining the Staining Resistance to Hydrogen Sulfide Gas
1. Scope—This SAE Recommended Practice is designed to reveal discoloration which may occur when nonmetallic materials used for trimming automobiles are exposed for a limited time to an atmospherecontaining hydrogen sulfide.
NOTE1—CAUTION-Hydrogen sulfide gas is extremely hazardous. Use of this substance may be fatal if proper precautions are not taken. This test method does not purport to address all of the safetyproblems associated with its use. lt is the responsibility of the user of this document to establishappropriate safety and health practices and determine the applicability of regulatory limitations priorto use.
NOTE 2—A fume hood and adequate ventilation should be provided at all times during testing.2.
