What rules and regulations govern the testing of containers used to store refrigerant evacuated from automotive ACs?
Transport Canada regulates the containers in which refrigerant gases are stored according to the Canadian Standards Association (CSA) B339, s.24.2.4, s. 24.2.5 and s.24.2.9. Normal pressure vessels must be re-tested every ten years but since used refrigerants are corrosive, pressure vessels storing them must be tested every five years. Testing can be done at any Transport Canada approved testing facility. For more information, contact Transport Canada at (416) 973-9820.
