Scope

This document applies to radio frequency disturbances emitted (radiated and conducted) by the following equipment: --- Lighting equipment (3.3.16); --- The lighting part of multifunctional equipment whose main function is lighting; Note 1: Examples are Lighting equipment for visible light communication and entertainment lighting. ---Ultraviolet and infrared radiation equipment for residential and non-industrial applications; ---Announcement signs; Note 2: Examples include neon-style advertising signs. --- decorative lighting; --- emergency signs. Not included in the scope of this document are: --- Components or modules intended to be installed in lighting equipment and not user-replaceable; Note 3: See CISPR30 (all parts) for built-in control devices. --- Lighting equipment operating in the industrial, scientific and medical frequency bands [ITU Radio Regulations Resolution 63 (1979) gives the definition]; --- Lighting equipment for aircraft and airports (runways, service facilities, platforms) ; --- Video identification; --- Mounting parts; --- Electromagnetic compatibility in the radio frequency range requires appliances that are clearly specified in other CISPR standards, even with built-in lighting functions. Note 4: Examples not included are:. --- Built-in lighting appliances as display backlights, dial lighting and signals; ---SSL displays; ---Range hoods, refrigerators, freezers; ---Copiers, slide projectors; ---Road motor vehicles lighting equipment (in the scope of CISPR12). The frequency range covered is 9kHz~400GHz. No testing is required at frequencies for which no limit values are specified in this document. For multi-function devices that are applicable to different clauses of this document and (or) other standards at the same time, the relevant functions need to meet the requirements of each clause or standard when working. For equipment outside the scope of this document and with lighting as a secondary function, it is only necessary to operate the lighting function when it is evaluated in accordance with its applicable standard, and it is not necessary to evaluate its lighting function in accordance with this document alone. Note 5: Examples of lighting as a secondary function of a product are range hoods, electric fans, refrigerators, freezers, ovens and TVs with ambient lighting. The radiated emission requirements in this document do not apply to intentional transmissions from radio transmitters as defined by the ITU, nor to any spurious emissions associated with these intentional transmissions. When "lighting equipment" and "EUT" are mentioned in this document, they all refer to electrical lighting and similar equipment included within the scope specified in this document. 1 GB/T17743—2021/CISPR15:2018
