1.1 * This International Standard specifies requirements for low-pressure hose assemblies intended for use with the following medical gases oxygen, nitrous oxide, medical air, helium, carbon dioxide, xenon, specified mixtures of the gases listed above, oxygen-enriched air, air for driving surgical tools, nitrogen for driving surgical tools, and for use with vacuum. It is intended in particular to ensure gas specificity and to prevent cross-connection between systems conveying different gases or vacuum. Hose assemblies intended for use with gas should operate at pressures up to 1 400 kPa and for vacuum between 90 kPa subatmospheric and 500 kPa positive pressure. 1.2 This International Standard does not specify the dimensions and allocation of the gas-specific inlet and outlet connectors for the hose assemblies. NOTE 1 – Specifications for the dimensions and allocation of diameter safety system (DISS) connectors can be obtained from the Compressed Gas Association Inc. (CGA).1 NOTE 2 – Specifications for the dimensions and allocation of sleeve indexed system (SIS) connectors are specified in AS 2896. NOTE 3 – Dimensions and allocation of non-interchangeable screw-threaded (NIST) connectors are specified in ISO 180822. NOTE 4 – Terminal units designed for quick connectors are specified in ISO 9170-1. 1.3 This International Standard does not specify requirements for coaxial hoses used for the supply and removal of air for driving surgical tools; 1.4 This International Standard does not specify the intended uses of hose assemblies.
