This is the fourth edition of CSA C373, Energy consumption test methods and limits for household dishwashers. It supersedes the previous editions published in 1992, 1989, and 1980. This Standard specifies the methods to be used to measure the energy consumption of electrically operated household dishwashers and also specifies maximum energy consumption limits (expressed as an energy factor). This edition provides a new procedure for testing the energy consumption of soil-sensing models, includes measurement of standby power consumption in the estimated annual operating cost and estimated annual energy use calculations for all dishwasher models, and adds high-efficiency energy consumption limits and new specifications for instrumentation. It also revises, based on new survey data on consumer practices, the number of cycles per year used for calculating the estimated annual operating cost.
This Standard specifies
(a) methods to be used in measuring the energy consumption of household dishwashers; and
(b) energy 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.
This Standard establishes a measure of energy performance and is not intended to preclude the exercise of ingenuity in the design or improvement of household dishwashers.
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.
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.
