Title:Recovery Equipment for Contaminated Refrigerant From Mobile Automotive Air Conditioning Systems
Issuing Committee:Interior Climate Control Service Committee
Scope: This standard is for R-1234yf recovery (extraction) only equipment for on-site refrigerant recovery from Mobile Air Conditioning (MAC) systems.NOTE: R-1234yf is a mildly flammable refrigerant [refrigerants called mildly flammable have a maximum burning velocity of < 0.10 m/s when tested at 23 掳C and 101.3 kPa] (ASHRAE 34 and ISO 817 Class 2L).
Rationale: This standard is for R-1234yf recovery (extraction) only equipment for on-site refrigerant recovery from Mobile Air Conditioning (MAC) systems.NOTE: R-1234yf is a mildly flammable refrigerant [refrigerants called mildly flammable have a maximum burning velocity of < 0.10 m/s when tested at 23 掳C and 101.3 kPa] (ASHRAE 34 and ISO 817 Class 2L).Product Code:SAE AMS2418
Title:Plating, Copper
