Scope

1.1 This Standard specifies the test methods to be used in measuring the energy efficiency of small direct-current (dc) and single- and three-phase alternating-current (ac) rotating motors. This Standard includes the following motor types:
(a) capacitor, permanent-split;
(b) capacitor, capacitor-start or capacitor-run;
(c) split phase;
(d) split phase start, capacitor-run;
(e) shaded pole;
(f) reluctance;
(g) polyphase induction;
(h) dc;
(i) permanent magnet;
(j) brushless dc; and
(k) inverter driven.

1.2 This Standard applies to
(a) dc and three-phase ac motors with output power rated greater than or equal to 0.186 kW and less than 0.746 kW at 1800 RPM (or equivalent); and
(b) single-phase ac motors rated greater than or equal to 0.186 kW. The test method specified in this Standard may be applied to smaller motors.

1.3 This Standard specifies quoting methods and allowable tolerances on nominal efficiency values.

1.4 This Standard applies only to motors rated as continuous duty.

1.5 SI units of measurement should be used in the application of this Standard; however, other units may be used for testing provided that they are used consistently.

1.6 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.
