DIN EN 50676 VDE 0400-60:2018-07

PrEN 50676-1 will define test methods and performance requirements for all electrical equipment used for the detection of refrigerant gases as defined in EN 378-1 as well as SF6 by means of concentration measurement. PrEN 50676-1 is addressed to the manufacturers of such equipment and the test laboratories which validate it. The tendency to use low-GWP refrigerant gases in the refrigeration and HVAC market (F-Gas Regulation) has led to the consideration of safety measures for low-GWP gases as some are flammable, toxic and can cause lack of oxygen. Some of these refrigerants have already been taken into account by other standards such as EN 60079-29-1:2016 for flammable gases and EN 45544 series for toxic gases in workplace atmospheres. This standard will consider the refrigerant gases in EN 378 series not already considered in the above cited standards. The level of safety shall be the same as in the already existing standards.
