Safety Standard of Electrical Appliances (K 61547)  
[IEC 61547 Ed.1:1995 -09 + A1:2000 -08] 
 
Equipment for General Lighting Purposes –  
EMC Immunity Requirements  
 
Introduction  
This technical standard for safety certification had been prepared by directly translating IEC 
61547 (Ed.1; published September, 1995) and IEC 61547 Amd.1 (Equipment for general light ing 
purposes – EMC immunity requirements; published August, 2000) without changing their 
technical contents and the forms for the standards. This standard was prepared in order to 
promptly accept and conform to the changes in the international standards, a nd to improve the 
current safety standard of electrical appliances management systems and standardization 
technology.  
1. Scope  
The EMC immunity requirements apply to lighting equipment which is within the scope of IEC 
Technical Committee 34, such as lamps,  auxiliaries and luminaries, intended either for 
connecting to low voltage electricity supply or for battery operation.  
Equipment listed below for which the immunity requirements are formulated in other IEC or 
CISPR standards are excluded from the scope o f this standard.  
 - Lighting equipment for vehicles  
 - Special purpose entertainment lighting controllers  
 - Lighting equipment that will be equipped to other instruments  
   • Lighting equipment for measuring or indicators  
   • Optical copying machines  
   • Slides and overhead projectors  
   • Visual display units  
 
But the parts of the multi -purpose lighting equipment, in which the accessories are working 
independently from other parts, should follow the requirements in this standard.  4 
 The requirements in th is standard are based on equipment as presented in the K 61000 -6-1, 
Generic Standard – Immunity for Residential, Commercial and Light Industrial Environments, 
but are currently being amended to practice illumination engineering.  
 
The lighting equipment com patible with the  requirements in this standard are deemed to work 
properly in the other environments.  In some special cases, the measurement may require a little 
more immunity. It is not possible to deal with all possibilities. Such requirements may be 
established by the agreement between the supplier and the consumer.  
 
This standard should be applied in conjunction with the related basic standards and/or product 
standards.  
 
2. Referenced Standards

3. Definitions of Terms  
The following definitions are used along with the ones defined in KS C IEC 60050(161) and KS 
C IEC 60050(845 ). 
3.1 Port: An electrical connecting terminal that interconnects the given equipment and the 
outside electronic system.  
3.2 Enclosure: The physical boundary of the equipment where electromagnetic waves radiate 
from or seep into.

            DC Power Port               Signal/Control Port  
<Figure 1> Port Example  
Note – In this standard, the DC power port to control power supply is considered as a signal port.  
4. Performance St andards  
4.1 The immunity test result or functional description on the performance standards during the 
test should be provided by the manufacturer, and should be recorded on the test report.  
The following are evaluated for the performance of lighting equip ment.  
  - The brightness of lamp or lighting equipment  
  - The control component, if the subject contains any control system or it is a control system 
itself  
  - Function of the starting device  
 
4.2 The following performance standards are applied to the li ghting equipment.  Lighting  
Equipment  6 
 Performance standard A  
The brightness should be consistent, and the control device should work as expected throughout 
the testing.  
Performance standard B  
The brightness may change while testing. However, it should be recovered to its init ial 
brightness within 1 minute after completion of the test.  
The control device does not need to perform any control action while testing. However, it must 
have the same control modes before and after the test. It is because the control modes before and 
after the test are same if there was no change to the given mode for the control action while 
testing.  
Performance standard C  
Some brightness changes may be allowed and the lamp may be turned off during and after the 
test. All of the original functionalities  must return to its normal conditions within 30 minutes 
after completion of the test, and the test sample may be retested or the control device may be 
retried if necessary.  
Additional requirement for lighting equipment with attached starting devices:  
Turn  the switch off once the test has completed, and when the switch is turned back on after 30 
minutes, the lighting equipment should work as expected.  
4.3 The change in the brightness should be checked by visual observations, however, the 
following method ma y be used when there are any uncertainties;  
The intensity of illumination should be measured by placing an illuminometer either at the centre  
of the main plane that is perpendicular to the lighting equipment or the lamp, or at the distance 
for appropriate operation. If the measured intensity of illumination did not exceed 15%, it is 
deemed unchanged.  
Make sure the intensity of ambient light does not affect the result of measurement.  
The directions should be followed so that the given performance standard o f the lamp can get 
recursive results.  
4.4 The phenomena of electromagnetic waves, by which the lifetime of light source will be 
affected, are excluded from this standard.  
5. Test Standards  
5.1 General matters  
Immunity requirements for the applicable equipm ent;
