scope:

This Standard applies to refrigerant-containing components that are intended to be used in field-installed systems in accordance with CSA B52 and that are charged with the refrigerant identified for use in the components.

This Standard applies to refrigerant-containing components that are intended for use in factory-assembled refrigeration or air-conditioning equipment and that are bound also by the pertinent requirements of CSA C22.2 Standards.

This Standard applies to refrigerant-containing components such as accumulators, condensers, evaporators, dryers, filters, heat exchangers, oil separators, liquid receivers, mufflers, liquid indicators, vibration eliminators, strainers, fusible plugs, and rupture members.

This Standard does not apply to

(a) electric valves, electric refrigeration controllers, or hermetic refrigerant motor-compressors; or

(b) electrical components of assemblies incorporating these refrigerant-containing components or accessories.

This Standard does not apply to refrigerant-containing components that are within the scope of CSA B51.

The values given in SI (metric) units are the standard. The values given in parentheses are for information only.

In CSA Standards, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; "may" is used to express an option or that which is permissible within the limits of the standard; and "can" is used to express possibility or capability. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
