IOR invites responses to EN378 revision
9th July 2025
UK: The Institute of Refrigeration says it will be developing a coordinated response to the proposed revision of EN378 standard and has urged input from the UK industry.
The revised EN378 standard, which specifies safety and environmental requirements for refrigerating systems and heat pumps, is now open for public consultation and will remain open until 26 August.
The changes proposed will have a significant impact on the design and installation of both factory built and site-installed systems.
It includes:
BS EN 378-1 – Refrigerating systems and heat pumps. Safety and environmental requirements. Part 1: Basic requirements, definitions, classification and selection criteria;
BS EN 378-2 – Refrigerating systems and heat pumps. Safety and environmental requirements. Part 2: Design, construction, testing, marking and documentation;
BS EN 378-3 – Refrigerating systems and heat pumps. Safety and environmental requirements. Part 3: Installation site and personal protection;
EN 378-5 Refrigerating systems and heat pumps. Safety and environmental requirements. Part 5: Safety classification and information about refrigerants.
You can submit comments via the BSI online portal, through https://standardsdevelopment.bsigroup.com/. A guide for the BSI online portal is available here.
The IOR technical committee will be developing a coordinated response on behalf of the Institute via the UK national committee RHE18 which includes several IOR member representatives. To contribute to the IOR’s response, please send your comments to ior@ior.org.uk by 11 August.
