1. SCOPE

The material defined by this specification is a hydrogenated nitrile butadiene rubber (HNBR) suitable for high temperature use, possessing goodresistancetorefrigerantHFC-134Aandpolyalkyleneglycol lubricants, and systems with R-12 and mineral oil. 2 . APPLICATION This specification was released originally for material used for O-rings used on the spring-lock quick-connect coupling in the air conditioning system.   3. REQUIREMENTS 3.1QUALITYSYSTEMREQUIREMENTS Material suppliers and part producers must conform to Quality System Requirements, QS-9000. Material specification requirements are to be used for initial qualification of materials. A Control Plan for ongoing production verification is required. This plan must be reviewed and approved by the relevant Ford Materials activity and/or Ford Supplier Technical Assistance (STA) prior to production parts submission. Appropriate statistical tools must be used to analyze process/product data and assure consistent processi
