This Standard does not apply to

(h) refrigeration products for use in recreational vehicles and other mobile equipment;
(i) custom-designed refrigerated storage cabinets manufactured as a special order for one customer only (franchisees are not considered separate customers). Customization in appearance, which does not affect the performance of the cabinet, does not constitute custom design for the purposes of this Standard; and

*Open and remote-condensing equipment used for displaying and merchandising food products is covered by CAN/CSA-C657.

1.5
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; and "may" is used to express an option or that which is permissible within the limits of the standard.
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 (nonmandatory) to define their application.

1.6
The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
