Reclaimed refrigerant that will be resold must be reprocessed to meet which purity standard?

Giải thích

Refrigerant intended for resale must be reclaimed to the AHRI 700 purity standard (historically called ARI 700), which sets the required purity for reclaimed product. ASHRAE 15 addresses refrigeration system safety, UL 1995 covers HVAC equipment safety, and NFPA 70 is the National Electrical Code. Meeting AHRI 700 is what allows used refrigerant to be legally sold to a new owner.
