ISO 5359:2008 PDF

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.
