Annotation

This International Standard specifies the requirements relating to the safety of persons and property for the design, construction, installation and operation of refrigerating systems.

It applies to all types of refrigerating systems in which the refrigerant is evaporated and condensed in a closed circuit, including heat pumps and absorption systems, except for systems using water or air as the refrigerant.2)

Individual safety standards for identifiable types of refrigerating systems may deviate from requirements set forth in this International Standard to accommodate particular needs, provided that there is no reduction in the level of safety achieved.

This International Standard is applicable to new refrigerating systems, extensions and modifications of already existing systems, and for used systems on being transferred to and operated on another site. Deviations are permissible only if equivalent protection is ensured.

It also applies in the case of the conversion of a system for another refrigerant, for example R 40 to R 12, or ammonia to R 22.
