  • SCOPE

    1 Scope

    1.1 These requirements cover nonelectrical refrigerant-containing components and accessories, intended for field installation in accordance with the Safety Code for Mechanical Refrigeration, ASHRAE 15, in refrigeration systems, air conditioning equipment, or both, charged with the refrigerants identified for use in the component or accessory. The requirements also apply to components and accessories intended for use by manufacturers in factory-assembled systems or units, in which case the component or accessory is also judged under the requirements for the individual system or unit.

    1.2 These requirements do not apply to:

    a)    Electric valves and electric refrigeration controllers, hermetic refrigerant motor-compressors, tubing fittings such as flare or compression type fittings, and the like, which are covered in or as part of separate, individual requirements.

    b)    Electrical components of assemblies incorporating these refrigerant-containing components or accessories, and

    c)    Pressure vessels bearing the ASME Code “U” symbol which are within the Scope of the ASME Boiler and Pressure Vessel Code, Section VIII.
