NF EN 737-3

La présente norme fixe les spécifications, les essais et la maintenance des réseaux de distribution de gaz médicaux non inflammables y compris les centrales et les systèmes d'alarmes. Il est particulièrement insisté sur les exigences de sécurité pour l'acheminement des gaz afin d'éviter toute erreur de branchement et inversion de distribution.

ISO 7396-1:2007 specifies requirements for design, installation, function, performance, documentation, testing and commissioning of pipeline systems for compressed medical gases, gases for driving surgical tools and vacuum in healthcare facilities to ensure continuous delivery of the correct gas and the provision of vacuum from the pipeline system. It includes requirements for supply systems, pipeline distribution systems, control systems, monitoring and alarm systems and non-interchangeability between components of different gas systems. ISO 7396-1:2007 is applicable to pipeline systems for the following medical gases: oxygen, nitrous oxide, medical air, carbon dioxide, oxygen/nitrous oxide mixtures; to pipeline systems for the following gases: oxygen-enriched air, air for driving surgical tools, nitrogen for driving surgical tools; and to pipeline systems for vacuum. ISO 7396-1:2007 also applies to extensions of existing pipeline distribution systems, modifications of existing pipeline distribution systems and modifications or replacement of supply systems or sources of supply.
