Pressure regulators for use with medical gases - Part 3: Pressure regulators integrated with cylinder valves (VIPRs) (ISO/DIS 10524-3:2025); German and English version prEN ISO 10524-3:2025
Abstract
This document specifies design, type testing, and marking requirements for cylinder valves with integrated pressure regulators [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. This 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.
