The Chinese documents consistent and corresponding with the normative international documents in this standard are as follows: GB/T 4365-2003 Electrotechnical terminology—Electromagnetic compatibility (IEC 60050 (161):1990, IDT) This standard was proposed by and is under the jurisdiction of the National Technical Committee 79 on Radio Jamming of Standardization Administration of China (SAC/TC 79). The previous editions of this standard are as follows: ——GB 15734-1995; ——GB 17743-1999, GB 17743-2007. Limits and methods of measurement of radio disturbance characteristics of electrical lighting and similar equipment 1 Scope This standard applies to the emission (radiated and conducted) of radiofrequency disturbances from: ——all lighting equipment with a primary function of generating and/or distributing light intended for illumination purposes, and intended either for connection to the low voltage electricity supply or for battery operation; ——the lighting part of multi-function equipment where one of the primary functions of this is illumination; ——independent auxiliaries exclusively for use with lighting equipment; ——UV and IR radiation equipment; ——neon advertising signs; ——street/flood lighting intended for outdoor use; ——transport lighting (installed in buses and trains). Excluded from the scope of this standard are: ——auxiliaries intended to be built into lighting equipment; ——lighting equipment operating in the ISM frequency bands (as defined in Resolution 63 (1979) of the ITU Radio Regulation); ——lighting equipment for aircraft and airports; ——apparatus for which the electromagnetic compatibility requirements in the radio-frequency range are explicitly formulated in other CISPR standards, even if they incorporate a built-in lighting function. Note 1: Examples of exclusions are: ——built-in lighting devices for display back lighting and signalling; ——range hoods, refrigerators, freezers; ——photocopiers, projectors; ——lighting equipment for road vehicle. The frequency range covered is 9 kHz to 400 GHz. Multi-function equipment which is subjected simultaneously to different clauses of this standard and/or other standards shall meet the provisions of each clause/standard with the relevant functions in operation. For equipment outside the scope of this standard and which includes lighting as a secondary function, there is no need to separately assess the lighting function against this standard, provided that the lighting function was operative during the assessment in accordance with the applicable standard. Note 2: Examples of equipment with a secondary lighting function may be range hoods, fans, refrigerators, freezers, ovens and TV with ambient lighting. The limits in this standard have been determined on a probabilistic basis to keep the suppression of disturbances within economically reasonable limits while still achieving an adequate level of radio protection and electromagnetic compatibility. In exceptional cases, additional provisions may be required. 2 Normative references The following referenced documents are indispensable for the application of this document.
