| Subject of the standard: | This document specifies general requirements for design, testing and performance, and describes the test methods that apply to portable, transportable and fixed equipment for the measurement of the oxygen concentration in gas mixtures indicating up to 25 % (v/v). The equipment, or parts thereof, may be intended for use in explosive atmospheres (see 4.1) and in mines susceptible to firedamp. This document applies to equipment intended for monitoring oxygen deficiency and enrichment. EXAMPLE Monitoring oxygen deficiency and/or enrichment includes: - protection of human health and safety in potentially oxygen deficient atmospheres; - fire protection by monitoring areas with reduced oxygen concentration; - fire protection by monitoring oxygen concentrations exceeding that of normal ambient air. This document also applies to equipment with an oxygen measuring function for explosion protection in the case of monitoring inertisation. |
