What is BS EN 378‑1 about?  

BS EN 378‑1 specifies the requirements for the safety of persons and property, provides guidance for the protection of the environment, and establishes procedures for the operation, maintenance, and repair of refrigerating systems and the recovery of refrigerants.  

BS EN 378‑1 as the first part of the relevant series specifies the classification and selection criteria applicable to refrigerating systems. 

BS EN 378‑1 on basic requirements, definitions, classification, and selection criteria for refrigerating systems and heat pumps is applicable: 

• To refrigerating systems, stationary or mobile, of all sizes except to vehicle air conditioning systems covered by a specific product standard  
• To secondary cooling or heating systems 
• To the location of the refrigerating systems 
• To replaced parts and added components after the adoption of this standard if they are not identical in function and in capacity. 

Note: BS EN 378‑1 is not applicable to refrigerating systems and heat pumps that were manufactured before the date of its publication. 

Who is BS EN 378‑1 for?  

BS EN 378‑1 on basic requirements, definitions, classification, and selection criteria for refrigerating systems and heat pumps is for:
