Preface This is the fourth edition of CAN/CSA-C22.2 No. 81, one of a series of Standards issued by the Canadian Standards Association under Part II of the Canadian Electrical Code. It is written in SI (metric) units and supersedes the previous editions, published in 1990 and 1979. This Standard has been revised to incorporate CSA TIL- C37, update reference standards to current versions, replace obsolete CSA No. 0.6 clauses with current CSA No. 0.17 clauses, and other minor editorial changes. For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface of the latest issue of CSA Standard CAN/CSA-C22.2 No. 0, General Requirements-Canadian Electrical Code, Part II. Scope 1.1 This Standard applies to cord-connected household and commercial irons of the steam or dry type, with or without automatic temperature control, for voltages of 250 V and less, designed to be used in accordance with the Rules of the Canadian Electrical Code, Part I. 1.2 This Standard applies to irons intended for general household and commercial clothes ironing use in nonhazardous locations. 1.3 This Standard does not apply to toy irons or to steam-producing equipment which is not an integral part of the iron. 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. Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.
