1.1 These requirements apply to portable germicidal equipment intended to expose the air and surfaces within an unoccupied area with uncontained ultraviolet (UV) energy. These requirements address equipment intended to remain stationary while in operation, and intended for use by ordinary persons in household and similar environments. The equipment may also produce visible light.
1.2 In this Outline, the UV overexposure risk is addressed via the following integral safeguards: 1) motion detection as a critical control function, and 2) activation cycle requirements and operating time limits. Additional safeguards may optionally be included by the manufacturer.
1.3 These requirements do not cover:
a) Hand-held equipment;
b) Equipment that does not use a motion detection function as a safeguard; or
c) Equipment that uses a wireless or remote control (i.e.: a control not physically part of the same device) to initiate or extend an operating cycle.
1.4 In the United States, products generating ultraviolet radiation are intended for use in accordance with Title 21 Code of Federal Regulations (CFR) Parts 1000 through 1004, and section 1005.25.
Note: These regulations include reporting of Accidental Radiation Occurrences, notification to FDA and customers of a radiation safety defect and corresponding plan for corrective action for FDA approval, and designation of a U.S. agent for imported lamps.
1.5 This Standard does not apply to UV germicidal equipment covered by other standards. Products not covered by this Standard include:
a) Laboratory and health care equipment with UV emitters covered by UL 61010 and CSA-C22.2 No. 61010, “Electrical Equipment for Measurement, Control, and Laboratory Use”;
b) UV Germicidal Equipment and Systems covered by UL 8802;
1.6 These requirements address risk of personal injury due to overexposure to UV emissions. To address other safety considerations (e.g.: risk of fire or electric shock, or personal injury risks besides UV) this outline of investigation shall be used in conjunction with CSA C22.2 No. 250.4 / UL 153, Portable Luminaires. All construction, performance and marking requirements in this standard apply unless specifically exempted or superseded by a requirement in this outline of investigation.
1.7 UV germicidal equipment that emit electromagnetic energy with wavelengths greater than 700 nm or less than 200 nm are not fully addressed by this Outline of investigation, and may require additional evaluation.
1.8 In this Outline, combined US and Canadian standard references are commonly separated by a slash (“ / ”). The CSA standard reference applies to products intended for use in Canada, and the UL standard reference applies to products intended for use in the United States.
1.9 Equipment features, functions or accessories not anticipated by this standard may require a separate evaluation.
