Preface This is the ninth edition of CSA C300, Energy performance and capacity of household refrigerators, refrigerator-freezers, freezers, and wine chillers. It supersedes the previous editions published in 2012, 2008, 2000, 1991, 1989, 1984, 1978, and 1977 under the title Energy performance and capacity of household refrigerators, refrigerator-freezers, and freezers and wine chillers. To provide improved clarity to the user, this edition has been re-organized by product section. This Standard is aligned, to the greatest extent possible, with the US Department of Energy (DOE) 10 CFR 430-September 15, 2011, which came into effect on September 15, 2014. In this Standard, some conversions from yard/pound to SI (metric) measurement, or the reverse, have been established as reasonable measures for the purposes involved, and are not necessarily direct hard or soft conversions. CSA gratefully acknowledges that the development of the CSA C300 Standard was made possible, in part, by the financial support of NRCan, BC Hydro, Manitoba Hydro, the Ontario Power Authority (OPA), Efficiency Nova Scotia, Québec Hydro, the Ontario Ministry of Energy, the Canadian Electricity Association (CEA), and Sask Power. Scope 1.1 This Standard applies to compact and household refrigerators, refrigerator-freezers, freezers, wine chillers, and hybrid wine chillers that are electrically operated on a 60 Hz alternating current, with a nominal supply voltage of 115 V. 1.2 This Standard applies to a) refrigerators and refrigerator-freezers with a maximum capacity of 1100 L (39 ft3) b) freezers with a maximum capacity of 850 L (30 ft3) c) wine chillers and hybrid wine chillers with a maximum refrigerated volume of 1100 L (39 ft3) 1.3 The requirements in this Standard are not applicable to electrically operated refrigerators using an absorption or thermoelectric refrigeration system. 1.4 The values given in SI (metric) units are the standard. Any values given in parentheses are for information only. 1.5 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. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
