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.
