Sets out safety requirements for oxygen analyzers, used in determining the oxygen level in breathing gas mixtures administered to patients. Both sampling and non-sampling oxygen analyzers are covered. Covers anaesthetic machines and breathing systems, ventilators, baby incubators, and oxygen concentrators (domiciliary or clinical). Excludes oxygen analyzers used in laboratory research applications. Has sections on protection against electric shock, mechanical hazards, excess radiation, explosions in medically used rooms, excess temperatures, fire etc., accuracy of operating data and protection against incorrect output, fault conditions, constructional and additional requirements.
