This European Standard establishes procedures for achieving and assessing the competence of persons who design, construct, install, inspect, test and commission, maintain, repair, decommission and dispose of refrigerating systems and heat pumps with respect to health, safety, environmental protection and energy conservation requirements.
This European Standard does not apply to those persons who carry out work on the basis of instructions if they are supervised by a competent person or operating the system according to the operation manuals or who carry out work that does not affect the refrigerant circuit.
This European Standard does not apply to persons carrying out work in a manufacturing process (from the initial design of the product to the complete manufacture of the product) provided the process is controlled and the methods used are checked by a competent person.
