IEC 61547:2020 pdf download.Equipment for general lighting purposes – EMC immunity requirements
1 Scope
This part of IEC 61547 which deals with electromagnetic immunity requirements, applies to lighting equipment which is within the scope of IEC technical committee 34, including apparatus such as lamps, luminaires, and modules. Excluded from the scope of this document are: – components or modules intended to be built into lighting equipment and which are not end-user replaceable; – equipment for which the electromagnetic compatibility requirements in the radio-frequency range are explicitly formulated in other product immunity standards, even if they incorporate a built-in lighting function. NOTE Examples of exclusions are: – – – – – – – equipment with built-in lighting devices for display back lighting, scale illumination and signaling; SSL-displays; range hoods, refrigerators, freezers; photocopiers, projectors; electronic switches for fixed installations; lighting equipment for road vehicles (within the scope of CISPR 12); lighting equipment for aircraft and airfield facilities. However, in multi-function equipment where the lighting function operates independently from other functions, the electromagnetic immunity requirements of this document apply to the lighting function only. Lighting equipment with a wireless control function are also within the scope of this document. However, the test is limited to the control of the lighting function only. Radio properties like frequency stability or spurious emissions are not assessed. EXAMPLE Colour/light level control via a wireless interface are meant to stay intact after an immunity test. Also included in the scope of this document is lighting equipment that interfaces with systems or installations other than common power supply networks. The requirements of this document are based on the requirements for domestic, commercial and light-industrial environments as given in IEC 61000-6-1:2016, but modified to lighting engineering practice. It can be expected that lighting equipment complying with the requirements of this document will operate satisfactorily in other environments. In some special cases, measures can be taken to provide higher immunity. In this document it is impracticable to deal with all these possibilities. Such requirements can be established by contractual agreement between supplier and purchaser.
4 Performance criteria
4.1 General  For the various immunity tests that apply, the performance of the following functions shall be assessed, as far as applicable or specified by the manufacturer: – the luminous intensity of the Iuminaire or of the light source(s); – the control function, for example on/off switching, light level setting, colour adjustment, wireless control.For these functions, three different levels of performance criteria are specified in 4.2. The functions assessed and the performance criteria for each individual test shall be noted in the test report. The effects of electromagnetic disturbances on the life of the equipment under test are excluded from this document. 4.2 Categorization of performance criteria The following three categories of performance criteria apply. a) Performance criterion A During the test, no change of the Iuminous intensity shall be observed and the regulating control, if any, shall operate during the test as intended. b) Performance criterion B During the test, the Iuminous intensity may change to any value. After the test, the Iuminous intensity shall be restored to its initial value within 1 min (30 min for high pressure gas discharge lamps). Regulating controls need not function during the test, but after the test, the mode of the control shall be the same as before the test, provided that during the test no mode changing commands were given. c) Performance criterion C During and after the test, any change of the luminous intensity is allowed and the light source(s) may be extinguished. After the test, within 30 min, all functions shall return to normal, if necessary by temporary interruption of the mains supply and/or operating the regulating control. The following additional requirement applies to lighting equipment incorporating a starting device: after the test, the lighting equipment is switched off for 30 min and back on again. The lighting equipment shall start and operate as intended. The application of the different performance criteria for the various types of tests and for different lighting equipment are specified in Clause 6.
