IEC 61547-2020 pdf free download.Equipment for general lighting purposes – EMC immunity requirements.
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 luminaire 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 luminous 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 luminous intensity may change to any value. After the test, the luminous intensity shall be restored to its initial value within 1 mm (30 mm 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.
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 mm, 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 mm and back on again. The lighting equipment shall start and operate as intended.IEC 61547 pdf free download.
