This International standard specifies safety requirements, certain functional requirements, and marking of valves and other components with similar bodies, hereinafter called valves, for use in refrigerating systems including heat pumps.

Valves in the sense of this standard include extension pipes.

The standard describes the procedure to be followed when designing valve parts subjected to pressure as well as the criteria to be used in the selection of materials.

The standard describes methods by which reduced impact values at low temperatures may be taken into account in a safe manner.

This standard applies to the design of bodies and bonnets for pressure relief devices, including bursting disc devices, with respect to pressure containment but it does not apply to any other aspects of the design or application of pressure relief devices.

This International Standard defines the activities related to refrigerating systems according to

EN 378-1, EN 378-2, EN 378-3, EN 378-4 and ISO 5149-1, ISO 5149-2, ISO 5149-3 and ISO 5149-4 and

the associated competence profiles and establishes procedures for assessing the competence of persons

who carry out these activities. Activities with regard to electricity are excluded.

NOTE As a refrigerating circuit is considered not to incorporate electrical and electronic systems, activities in

this area are not part of this standard. For competences on electrical and electronic systems, it is recommended to

refer to national regulations or appropriate European or national standards. 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 on health, safety and environment (e.g. energy efficiency).

NOTE The standard is not a training programme .
