1.2 This specification covers safety requirements for oxygen analyzers, as defined in 3.11 (in this specification) intended for use in determining the oxygen level in breathing gas mixtures administered to patients. Both sampling and non-sampling oxygen analyzers are covered.

1.3 The field of application includes, but is not limited to:

1.3.1 Anesthetic machines and breathing systems,

1.3.2 Ventilators,

1.3.3 Baby incubators, and

1.3.4 Oxygen concentrators (domiciliary or clinical).

1.4 Oxygen analyzers intended for use in laboratory research applications are outside the scope of this specification.

1.5 The values stated in SI units are to be regarded as the standard.

1.6 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
