Low-pressure hose assemblies for use with medical gases - Third Edition
 N 5359

Annotation

* 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.

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.

This International Standard does not specify:

— requirements for coaxial hoses used for the supply and disposal of air for driving surgical tools;
