Preface:This is the fifth edition of CSA C22.2 No. 187,Electrostatic air cleaners, one of a series of Standards issued by CSA Group under Part II of theCanadian Electrical Code. It supersedes the previous editions, published in 2015, 2009, 1986, and 1982.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.Scope:1.1This Standard applies toa) electrostatic air cleaners intended to remove dust and dirt from the air and intended for general indoor residential and commercial use;b) air ionizer type air cleaners;c) other similar ionizing equipment; andd) duct-mounted type electrostatic air cleaners, air ionizers, and other similar ionizing equipment intended for general indoor residential use.1.2This Standard applies to equipment for commercial use that intentionally produces ozone in a temporarily unoccupied space.1.3This Standard applies to cord-connected and permanently-connected equipment operating at nominal supply voltages up to 600 V, single-phase or polyphase, that is intended to be installed or used in accordance with CSA C22.1,Canadian Electrical Code, Part I.1.4This Standard applies to portable and duct-mounted air-cleaning devices that incorporate a UV (ultraviolet) lamp that emits UV radiation between 100 and 280 nm (UVC).1.5This Standard does not apply to electrostatic air cleaners for use in hazardous locations or in atmospheres defined as hazardous by theCanadian Electrical Code, Part I.1.6This Standard does not apply to air cleaners designed to remove particles other than dust and dirt normally found in heating and ventilating systems.1.7This Standard does not specify requirements for the effectiveness of air cleaners with respect to the removal of airborne particles.1.8This Standard does not apply to electrostatic air cleaners intended for industrial use.1.9This Standard does not apply to air cleaners for residential use that are designed to generate ozone intentionally.1.10This Standard does not apply to ozone generators, and/or devices intentionally using ozone to treat or condition air, designed exclusively to be connected to air duct systems. 1.11 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.
