Can any one advise supplier / specification for refrigerant identification labels for pipework?
There are many listed for HVAC applications & ammonia etc but I can find no standard for HFC refrigeration systems.
Is there a particular colour for types of refrigerants?
Is there a british standard or EN?
I have seen some small stick-on type from HRP. These seen small & not substantial in comparison to the HVAC indusrty?
