4 Performance criteria
4.1 A functional description of performance criteria, during or as a consequence of the immunity testing, shall be provided by the manufacturer and noted in the test report.
The performance of lighting equipment shall be assessed by monitoring:
— the luminous intensity of the luminaire or of the lamp(s);
— the functioning of the control in the case of equipment which includes a regulating control or concerns the regulating control itself;
— the functioning of the starting device, if any.
4.2 The performance criteria given hereafter apply to lighting equipment.
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. 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 lamp(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 andlor operating the regulating control.
Additional requirement for lighting equipment incorporating a starting device: After the test, the lighting equipment is switched off. After half an hour, it Is switched on again. The lighting equipment shall start and operate as intended.
4.3 A change of luminous intensity may be checked by visual observation but, in case of doubt, the following applies.
The luminous intensity of a luminaire or of the lamp(s) shall be measured by means of a illuminance (lux) meter which is positioned in an axis perpendicular to the main plane of the luminaire or lamp(s), in its centre and at a distance for proper operation of the lux meter. The luminous intensity shall be deemed to be unchanged if the measured intensities do not deviate by more than 15 %.
Care shall be taken to ensure the ambient light level does not influence the measurement results.
Precautions to achieve reproducible results given in the relevant lamp performance standards shall be observed.
4.4 The effects of electromagnetic phenomena (as described in this standard) upon the life of the equipment under test are excluded from this standard.
5 Test specifications
5.1 General
Immunity requirements for equipment defined within the scope concern:
— electrostatic discharges;
— continuous and transient disturbances:
— radiated and conducted disturbances;
— mains supply-related disturbances.
They are given in Subclauses 5.2 to 5.9 on a port by port basis.
Tests are applied to the relevant ports of the equipment as indicated in the respective subclauses. For the purposes of this standard, d.c. power ports for supplying regulating controls are considered to be signal ports. Tests shall be conducted in a well-defined and reproducible manner. Tests shall be carried out as single tests in sequence, The sequence of testing is optional.
It may be determined from consideration of the electrical characteristics and usage of particular equipment that some of the tests are inappropriate and therefore unnecessary. In such cases it is required that the decision not to test be recorded in the test report.
The description of the test, the test generator, the test methods and the test set-up are given in the basic standards, which are referred to in the relevant subclauses.
Test levels are generally based on level 2 values as recommended in the basic standards.BS/EN 61547-2009 pdf download.
