GB/T 45899-2025 Anaesthetic and respiratory equipment—Compatibility with oxygen
Abstract
This document specifies the requirements for the compatibility of materials, components, and equipment in anesthesia and respiratory applications with oxygen, under normal or single-fault conditions where the gas pressure exceeds 50 kPa.
Note 1: Additionally, this document provides general guidance for selecting materials and components based on existing data on oxygen compatibility, as well as for risk analysis of the toxicity of combustion and/or decomposition products.
Note 2: This document proposes compatibility characteristics at all stages of design, production, maintenance, and handling, including cleanliness, flame retardancy, and the toxicity of combustion and/or decomposition products.
This document applies to anesthesia and respiratory equipment. For example: medical gas piping systems, pressure regulators, terminals, medical supply units, flexible connections, flowmeter devices, anesthesia workstations, and ventilators.
This document does not apply to biocompatibility.
