This standard applies to the selection of an appropriate cylinder valve outlet connection for medical gases for pressures up to 3000 psi (20 680 kPa) at 70 Â°F (21.1 Â°C). It does not apply to industrial gas mixtures, cylinders manifolded in transport and use, or to mixtures at higher pressures. Both threaded and pin-indexed connection assignments are included with reference to V-1.
This revision replaces the use of limited standards with alternate standards for the purpose of assuring only one connection assignment will be appropriate. This revision brings consistency with ISO 407:2004, to standardize pin-indexed yoke-type valve connections globally .
