Le présent document amende toutes les exigences de la NF EN 739, de mars 1998, pour rendre les flexibles basse pression aptes à l'emploi du mélange oxyde nitrique/azote.
<p>ISO 5359:2008 specifies requirements for low-pressure hose assemblies intended for use with the following medical gases:</p> <ul> <li>oxygen;</li> <li>nitrous oxide;</li> <li>medical air;</li> <li>helium;</li> <li>carbon dioxide;</li> <li>xenon;</li> <li>specified mixtures of the gases listed above;</li> <li>oxygen-enriched air;</li> <li>air for driving surgical tools;</li> <li>nitrogen for driving surgical tools;</li> <li>vacuum.</li> </ul> <p>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.</p> <p>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.</p>
