Title:Hfc-134a (R-134a) Refrigerant Recovery Equipment for Mobile Automotive Air-Conditioning Systems (STABILIZED Nov 2011)
Issuing Committee:Interior Climate Control Committee
Scope:The purpose of this SAE Standard is to provide equipment specifications for the recovery of HFC-134a (R-134a) refrigerant to be returned to a refrigerant reclamation facility that will process it to the appropriate ARI 700 Standard or allow for recycling of the recovered refrigerant to SAE J2210 specifications by using Design Certified equipment of the same ownership. It is not acceptable that the refrigerant removed from a mobile air-conditioning (A/C) system, with this equipment be directly returned to a mobile A/C system.This information applies to equipment used to service automobiles, light trucks, and other vehicles with similar HFC-134a (R-134a) A/C systems.【英文标准名称】:Free-cuttingsteels-Technicaldeliveryconditionsforsemi-finishedproducts,hot-rolledbarsandrods;GermanversionEN10087:1998
