CSA C393-12:2017 pdf download.Test methods for measuring power consumption in low and idle power modes of commercial and industrial equipment
1.1 CSA C393-12 specifies methods for measuring electrical power consumption of equipment intended for use in commercial and industrial application when in low power mode(s) (i.e., standby mode, off mode,and network mode) and idle mode.
This Standard is applicable to electrical products with a rated input voltage or voltage range that lies wholly or partly in the range 100 V a.c. to 347 V a.c. for single phase input and 130 V a.c. to 7200 V a.c for other inputs.
Notes:
(1) The measurement of energy consumption and performance of products during intended use are generally specified in the relevant product standards and are not covered by this Standard.
(2) Where this Standard is referenced by performance standards or procedures, these should define and name the relevant low power modes (see Clause 3) to which this Standard is applied.
(3) The inclusion of d.c. powered products within the scope of this Standard is under consideration.
1.2 This Standard does not specify safety requirements. It does not specify minimum performance requirements nor does it set maximum limits on power or energy consumption.
The methods described in this Standard are not intended to be used to measure power consumption of products during in-service mode, as these are generally covered by other product standards (see Bibliography for some examples), although the measuring techniques, measurement uncertainty determination, and test equipment specifications may be adapted for such measurements with careful review.
1.3 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.
Notes:
(1) The low power mode and active mode categories in this Standard are intended to provide guidance for the development of specific mode definitions in other product standards.
(2) Annex A provides guidance on expected modes found in various product configurations and designs based on their circuitry and layout, but it does not define these modes. Annex A also provides background and guidance to users of this Standard regarding the development of mode definitions for specific products.CSA C393-12 pdf download.
