CSA Group CAN/CSA-C373-14 National Standard of Canada (reaffirmed 2024) Energy performance and water consumption of household dishwashers

Preface

This is the fifth edition of CSA C373, Energy performance and water consumption for household dishwashers. It supersedes the previous editions published in 2004, 1992, 1989, and 1980.

Changes to this edition include

a) a new procedure for testing the energy consumption of soil-sensing models;

b) measurement of standby power consumption in the estimated annual energy use calculations for all dishwasher models; and

c) addition of high-efficiency energy consumption limits and new specifications for instrumentation.

CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of Natural Resources Canada (NRCan), BC Hydro, the Canadian Electricity Association (CEA), Efficiency Nova Scotia, Hydro-Québec, Manitoba Hydro, the Ontario Ministry of Energy, the Ontario Power Authority (OPA), and Sask Power.

This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.

This Standard was prepared by the Subcommittee on the Performance of Dishwashers, under the jurisdiction of the Technical Committee on Residential Equipment and the Strategic Steering Committee on Performance, Energy Efficiency, and Renewables, and has been formally approved by the Technical Committee.

This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

Notes:

1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.

2) Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose.

3) This Standard was developed by consensus, which is defined by CSA Policy governing standardization — Code of good practice for standardization as “substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity”. It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with all clauses of this Standard.

4) To submit a request for interpretation of this Standard, please send the following information to [email protected] and include “Request for interpretation” in the subject line:

a) define the problem, making reference to the specific clause, and, where appropriate, include a graphical image;

b) provide an explanation of circumstances surrounding the actual field condition; and

c) where possible, phrase the request in such a way that a specific “yes” or “no” answer will address the issue.

Committee interpretations are processed in accordance with CSA Directives and guidelines governing standardization and are available on the Current Standards Activities page at standardsactivities.csagroup.org.

5) This Standard is subject to review within five years from the date of publication. Suggestions for its improvement will be referred to the appropriate committee. To submit a proposal for change, please send the following information to [email protected] and include “Proposal for change” in the subject line:

a) Standard designation (number);

b) relevant clause, table, and/or figure number;

c) wording of the proposed change; and

d) rationale for the change.

1 Scope

1.1

This Standard specifies

a) methods to be used in measuring the energy and water consumption levels of household dishwashers; and

b) maximum and high efficiency energy and water consumption limits for household dishwashers.

1.2

This Standard applies to household electrically-powered automatic dishwashers designed for a 60 Hz ac supply and a nominal system voltage not exceeding 250 V.

1.3

This Standard does not apply to commercial, industrial, or institutional dishwashers.

1.4

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 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. Legends to equations and figures are considered requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.5

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