This document sets out the requirements relating to safety of persons, property, but not goods in storage, and local and global environment for: stationary and mobile refrigerating systems of all sizes, including heat pumps, secondary cooling or heating systems, and the location of these refrigerating systems. It is applicable to new refrigerating systems. Parts dealing with maintenance, repair, operation, training, recovery, reuse and disposal also apply to existing systems. Owners or users of existing refrigerating systems are required to consider the safety and environmental aspects of this draft standard and implement more stringent requirements as far as they are reasonably practivable.
