Draft Details

1.1 General

The standard  provides a unified best practice for measuring and reporting the power consumption of a range of three phase low voltage equipment where the equipment is not delivering an intended service to a user in commercial and industrial applications. The specified test methods are applicable for a single equipment and  not to be used for a set of equipment.

NOTE1  The measurement of power consumption and performance of equipment during an intended use (active mode) are generally specified in the relevant equipment standards and are not covered by this standard.

NOTE2  Where this standard is referenced by performance standards or procedures, these should define and name the relevant mode (see clause 3) to which this test procedure is applied.

NOTE3 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.

1.2 Inclusions

The standard is applicable to the following products:

Three-phase AC electrical energy consuming commercial and industrial equipment with rated voltage up to 690 V and not in active mode

Air-cooled equipment

1.3 Exclusions

This Standard is not intended for use for the following systems:

DC, single, or two phase electrical commercial and industrial equipment

Household electrical appliances covered by CAN-CSA-C62301-11 (R2021)

Water-cooled equipment

Non electrical energy consuming commercial and industrial equipment such as backup generators

1.4 Measurement units

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 and converted to SI units for the reporting purposes.

1.5 Terminology

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with this 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 this Document.

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.
