Introduction of GB/T 17743-2021

Limits and methods of measurement of radio disturbance characteristics of electrical lighting and similar equipment 1 Scope This document applies to the emission (radiated and conducted) of radio frequency disturbances from: ——lighting equipment (3.3.16); ——the lighting part of multi-function equipment where this lighting part is a primary function; Note 1: Examples are lighting equipment with visible-light communication, entertainment lighting. ——UV and IR radiation equipment for residential and non-industrial applications; ——advertising signs; Note 2: Examples are neon tube advertising signs. ——decorative lighting; ——emergency signs. The following are excluded in the scope of this standard: ——components or modules intended to be built into lighting equipment and which are not user-replaceable; Note 3: See CISPR 30 (all parts) for built-in control gear. ——lighting equipment operating in the industrial, scientific, and medical (ISM) frequency bands (as defined in Resolution 63 (1979) of the ITU Radio Regulation); ——lighting equipment for aircraft and airfield facilities (runways, service facilities, platforms); ——video signs; ——installations; ——equipment 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 4: Examples of exclusions are: ——equipment with built-in lighting devices for display back lighting, scale illumination and signaling; ——SSL displays; ——range hoods, refrigerators and freezers; ——photocopiers, and slide projectors; – lighting equipment for road vehicles (in scope of CISPR 12). The frequency range covered is 9 kHz to 400 GHz. No measurements need to be performed at frequencies where no limits are specified in this document. Multi-function equipment which is subjected simultaneously to different clauses of this document and/or other standards need to meet the provisions of each clause/standard with the relevant functions in operation. For equipment outside the scope of this document and which includes lighting as a secondary function, there is no need to separately assess the lighting function against this document, provided that the lighting function was operative during the assessment in accordance with the applicable standard. Note 5: Examples of equipment with a secondary lighting function can be range hoods, fans, refrigerators, freezers, ovens and TV with ambient lighting. The radiated emission requirements in this document are not intended to be applicable to the intentional transmissions from a radio transmitter as defined by the ITU, nor to any spurious emissions related to these intentional transmissions. Within the remainder of this document, wherever the term "lighting equipment" or "EUT" is used, it is meant to be the electrical lighting and similar equipment falling in the scope of this document as specified in this clause.   2 Normative references The following documents contain provisions which, through reference in this text, constitute indispensable provisions of this document.
