Electrical equipment used for detection and concentration measurement of refrigerant gases. Performance requirements and test methods1 Scope This document specifies general requirements for the construction, testing and performance of electrically operated refrigerant fixed gas detection equipment in safety applications. This document does not specify requirements for portable locating leak detectors for refrigerant application as already covered by EN 14624: 2012. This document is applicable to equipment whose primary purpose is to provide an indication, alarm and or other output

the level of corrosive (and acid) gases is determined by measurement of hydrochloric acid (HCl) in accordance with BS EN 50267‑2‑1

the CE mark is not a mark of conformity with a standard but only a self-declaration concerning the CPD essential requirements
