Safety Standards and Components for flammable refrigerants

Asercom has published a guide for the safe handling of components in the use of flammable refrigerants. 

The purpose of this guideline is to provide common interpretation of the demands to and application of components in vapour compression systems which use flammable refrigerants
within the frames of the HVACR standards in the EU. As flammable refrigerants play a big role in the phase down of refrigerants related emissions this guideline will facilitate the design of low GWP systems. 

This guideline is valid for the components comprising a vapour compression system using flammable refrigerants i.e. valves, heat exchangers, compressors and other mechanical, electronic and electro-mechanical controls. This guideline covers only components for systems to operate in non-hazardous areas i.e. non ATEX areas/ It should be noticed that vapour compression systems serve in a broad variety of applications which may be designed operated under special conditions.
