This document will define test methods and performance requirements for all electrical equipment used for the detection of the refrigerant gases as defined in EN 378 1 as well as SF6 by means of concentration measurement.
NOTE 1   For the purposes of this standard, the term “refrigerant gases” includes refrigerant gases defined in EN 378 1 as well as SF6.
This document specifies general requirements for the construction, testing and performance of electrically operated refrigerant gas detection equipment in safety applications.
The application is intended to also consider electrical equipment in refrigeration systems according to the F-Gas Regulation.
This document is applicable to apparatuses whose primary purpose is to provide an indication, alarm and/or other output function to warn of the presence of refrigerant gases or SF6 in an industrial or commercial environment and, in some cases, to initiate automatic or manual protective actions. It is applicable to apparatuses in which the sensor automatically generates an electrical signal when gas is present.
Some of these refrigerant gases could be also classified as toxic gases or vapours intended for exposure measurement or as flammable gases.
In accordance with the classification of the gas and the tasks covered in EN 60079-29-1:2016, EN 45544-2:2015 and EN 45544-3:2015 for refrigeration application, three different types of equipment are provided (see also Table A.1).
-   Type I: Refrigerant gas detection equipment for A2, A2L, R717, A3, B3 refrigerants as per safety class in EN 378 1:2016 Annex E in accordance with explosion protection. The equipment shall follow the existing performances in EN 60079 29 1:2016 for ranges up to 20 % LEL and or 0 % – 100 % LEL.
-   Type II: Refrigerant gas detection equipment for A1, A2L, B1, B2L refrigerant gases as per safety class in EN 378 1:2016 Annex E in accordance with OEL values. The equipment shall follow the performances in EN 45544-2:2015.
-   Type III Refrigerant gas detection equipment not covered by Type I or Type II for refrigerant gases A1, A2L, B1, B2L as per safety class in EN 378 1:2016 Annex E. The equipment shall follow the performances in EN 45544-3:2015
This document does not apply to non-refrigerant applications:
-   monitoring of combustible gases in the range up to 20 % or up to 100 % of the LEL level, covered by EN 60079 29 1:2016;
-   workplace atmospheres, covered by the EN 45544 series.
This document is not applicable to equipment:
-   used for air pollution monitoring;
-   external sampling systems;
-   open path gas detection;
-   residential applications;
-   process control;
-   leakage (emission rate monitoring) detection system for SF6.
NOTE 2   SF6 equipment is typically located in large and ventilated rooms or outdoor, so that monitoring SF6 concentrations in the surrounding atmosphere does not permit a reliable detection of leakages.

This document specifies general requirements for the construction, testing and performance of electrically operated refrigerant fixed gas detection equipment in safety applications. This document will 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 function to warn of the presence of refrigerant gases in an industrial or commercial environment and, in some cases, to initiate automatic or manual protective actions. It is applicable to equipment in which the sensor automatically generates an electrical signal when gas is present. This standard does not apply to gas detection equipment: — for non-refrigerant application; — used for air pollution monitoring; — sampling systems, which are not integral part of the gas detection equipment; — open path gas detection; — residential applications; — process control; — for applications in mines; — portable locating leak detectors for refrigerant application.
