This European Standard defines the activities related to refrigerating circuits and the associated competence profiles and establishes procedures for assessing the competence of persons who carry out these activities. NOTE: As a refrigeration circuit is considered not to incorporate electrical and electronical systems activities in this area are not part of this standard. For competences on electrical and electronical systems see EN 50110. This European Standard does not apply to persons carrying out work on self contained refrigerating systems as defined in EN 378-1 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 an organisation or individual responsible for the compliance with statutory requirements of health, safety and environment.
