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;
-- vacuum.
It is intended in particular to ensure gas-specificity and to prevent cross-connection between systems conveying different gases. These hose assemblies are intended for use at maximum operating pressures of less than 1 400 kPa.
1.2 This International Standard specifies the allocation of (NIST), (DISS), (SIS) connectors to medical gases and specifies the dimensions of non-interchangeable screw-threaded (NIST) connectors.
1.3 This International Standard does not specify:
-- requirements for coaxial hoses used for the supply and disposal of air for driving surgical tools;
-- requirements for electrical conductivity.
