Low-pressure hose assemblies for use with medical gases ISO 5359:2008

Publication date:   May 28, 2008

Scope

ISO 5359:2008 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 hoses assemblies are intended for use at maximum operating pressures less than 1 400 kPa.
ISO 5359:2008 specifies the allocation of non-interchangeable screw-threaded (NIST) connectors, diameter-index safety system (DISS) connectors and sleeve indexed system (SIS) connectors to medical gases and specifies the dimensions of non-interchangeable screw-threaded (NIST) connectors.
