CSA C22.2 NO.187-2015 Electrostatic air cleaners.
The following definitions apply in this Standard:
Accessible part —
a) a part located such that it can be contacted by a person either directly or using the probe specified in Figure 3; or
b) a part that is not recessed the required distance behind an opening.
Air ionizer — an appliance that uses high voltage to ionize air molecules to remove dirt and dust from the air.
Commercial use — use of a product in a location other than a residential occupancy, where the same person does not occupy the space on a continual basis.
Note: An office setting Is an example of a commercial occupancy.
Duct-type air cleaner — an air cleaner intended for permanent installation in and at adjoining ducts of heating, air-conditioning, or ventilation systems.
Electrostatic air cleaner — an appliance intended to remove dust and dirt from the air. Note: A complete electrostatic air cleaner can consist of a high-voltage power supply, controls, on ionizer-collector cell, and other components.
Exposed — as applied to non-current-carrying conductive parts, the parts that can be touched by the user in the normal use or adjustment of equipment, including those parts that can be touched accidentally.
Hazard — a potential source of harm.
Hazardous condition — a situation that would put a person in a potential source of harm.
Ionizer-collector cell — the component of an electrostatic air cleaner that is energized by the power supply and through which the air to be cleaned is passed.
Line-voltage — the voltage supplied by a power line, measured at the point of use.
Live part — a part that carries a current greater than 0.5 mA at a voltage exceeding 30 V rms or 42.4 V dc.
Occupied space — an area used or intended to be used by one or more persons on a full-time or part-time basis.
Ozone-level control system — a system designed to control the concentration of ozone generated by a product.CSA C22.2 NO.187 pdf download.
