Guide to pressure equipment safety and A2Ls

UK: The Institute of Refrigeration has published new guidance explaining the requirements and responsibilities contained within the Pressure Equipment (Safety) Regulations and Pressure Equipment Directive (PED), and who they affect.

With components being supplied by a manufacturer for site installation (assembly) by a specialist third party contractor, the contractor might not realise that it then becomes the manufacturer of the assembly making it “an integrated and functional whole” under PE(S)R. 

The adoption of R32 and other A2L refrigerants, classified as PE(S)R group 1 fluid (“dangerous”), moves many systems from SEP (sound engineering practice) or hazard category 1 into hazard category 2 or higher. The systems which are category 2 or higher must comply with the PE(S)R and must be assessed by an approved Conformity Assessment Body or under an assessment scheme which has been certified by a Conformity Assessment Body.

The three-page document – Guidance Note 36 – explains all and can be downloaded for free from the IoR website.
