1.1
This Standard applies to devices intended to potentially remove/reduce airborne particulate matter, VOCs, or microorganisms from the air in indoor residential and commercial with self-contained or duct-mounted applications.
1.2
This standard applies to powered:
a) extra-low and low voltage electrostatic air cleaners
b) ionizing air cleaners
c) photocatalytic oxidizer type air cleaners
d) UV (ultraviolet) devices that emit UVC radiation between 100 and 280 nm
1.3
This Standard does not apply to unpowered air filters.
1.4
This 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.
1.5
This standard also applies to products powered by Universal Serial Bus (USB) supply source and rechargeable batteries.
1.6
This Standard does not apply to electrostatic air cleaners for use in hazardous locations or in atmospheres defined as hazardous by the Canadian Electrical Code, Part I.
1.7
This Standard does not specify requirements for the effectiveness of air cleaners with respect to the removal of airborne particles.
1.8
This Standard does not apply to electrostatic air cleaners intended for industrial use.
1.9
This Standard does not apply to air cleaners for residential use that are designed to generate ozone intentionally.
1.10
This 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.
