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 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.
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.
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.
This Standard does not apply to commercial, industrial, or institutional dishwashers.
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.
The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
