This SAE Standard covers reinforced rubber, reinforced thermoplastic, or otherwise constructed hose, or hose assemblies, intended for conducting liquid and gaseous refrigerants for service connections from mobile air conditioning systems to service equipment such as a manifold gauge set and vacuum pumps or for use internally, in charging stations or service equipment intended for use in servicing mobile air-conditioning systems. The hose shall be designed to minimize permeation of refrigerants and contamination of refrigerant passing there through and to be serviceable over a temperature range of -30 to 95 degrees C. Hose working pressures shall be at least 3.4 MPa and the minimun burst pressure shall be at least 5 times.
