Abstract / 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.
