Product Code:SAE J1990
Title:Recovery and Recycle Equipment for Mobile Automotive Air-Conditioning Systems (STABILIZED May 2011)
Issuing Committee:Interior Climate Control Committee
Scope:The purpose of this SAE Standard is to provide equipment specifications for CFC-12 (R-12) recycling equipment. This information applies to equipment used to service automobiles, light trucks, and other vehicles with similar CFC-12 (R-12) air-conditioning (A/C) systems. Systems used on mobile vehicles for refrigerating cargo that have hermetically sealed systems are not covered in this document. The equipment in this document is intended for use with refrigerant that has been directly removed from, and intended to be returned to, a mobile A/C system. Should other revisions due to operational or technical requirements occur, this document may be amended.
