1. Scope
1.1 This International Standard specifies requirements for low-pressure hose assemblies intended for use with the following medical gases;
—oxygen;
—Nitrous oxide;
—air for breathing;
—helium;
—xenon
—specified mixtures of the gases listed above;
—air for driving surgical tools;
—nitrogen for driving surgical tools;
—nitric oxide/nitrogen mixtures;
—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 to be used at pressure less than 1 400 kPa.
1.2 This International Standard specifies the allocation of non-interchangeable screw-threaded (NIST) connectors and diameter-index safety system (DISS) connectors to medical gases and specifies the dimentionsof non-interchangeable screw-threaded (NIST) connectors.
1.3 This International Standard does not specify:
—requirements for coaxial hoses used for the supply and disposal of air for driving surgical tools;
—requirements for electrical conductivity.
1.4 This International Standard does not specify the intended uses of hose assemblies.
