Refrigerant codes of practice
The Institute of Refrigeration has completely revised its A1/A2 and A3 refrigerant codes of practice following the publication of the revised European refrigeration safety standard BS EN 378:2008 ‘Refrigerating systems and heat pumps — safety and environmental requirements.
The suite of four IOR codes now includes: carbon dioxide; ammonia; A2 and A3 refrigerants (flammable halocarbons and hydrocarbons; A1 refrigerants (non-flammable halocarbons).
The institute’s technical committee acted as a peer reviewer for the revision of BS EN 378:2008.
