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.
