1.2
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
Air cleaners for household use that are designed to generate ozone intentionally are outside the scope of this Standard.
