Scope

This document specifies design, type testing, and marking requirements for cylinder valves with integrated pressure regulators [as defined in 3.26 and referred to hereafter as valves with integrated pressure regulators (VIPRs)].Medical VIPRs are designed to be mounted on medical gas cylinders, allowing them to be filled with medical gases for subsequent use as a supply source for other medical devices, such as emergency ventilators, or for the direct administration of medical gases to a patient via an integral flow control device, when fitted.Examples of medical gases include oxygen, medical air and oxygen/nitrous oxide mixtures.Intended use of VIPRs may also encompass the supply of air or nitrogen for driving surgical tools.NOTE See annex B for their specific requirementsThis document applies to VIPRs mounted on refillable cylinders with a working pressure up to 30 000 kPa (300 bar) intended to be filled in cylinder filling facilities or on self-filling systems as used in homecare applications.VIPRs covered by this document are pressure pre-set and provided with a pressure outlet and/or pre-set flow outlet(s).VIPRs used for self-fill systems used in homecare are not covered by this standard, but it can be used as a guide.NOTE  The conditions of use for these VIPRs vary significantly, particularly in terms of filling frequency and usage, which can occur daily throughout their lifetime.
