4.7.3 TEST SETUP 

 
NOTE: 
FLOOR-STANDING EQUIPMENT 
The equipment to be tested is placed on an insulating support of 0.1 meters height above a 
ground reference plane. All relevant cables shall be provided with the appropriate coupling and 
decoupling devices at a distance between 0.1 meters and 0.3 meters from the projected geometry 
of the EUT on the ground reference plane.

 The EUT and support equipment, are placed on a table that is 0.8 meter above a metal ground 

plane measured 1m*1m min. and 0.65mm thick min.   
The other condition as following manner: 

a. The equipment cabinets shall be connected to the safety earth directly on the GRP via the 

earth terminal of the EUT. 

b. The cables supplied or recommended by the equipment manufacturer shall be used. 1 meter 

of all cables used shall be exposed to the magnetic field.

4.8.3 TEST SETUP 

Note: 
TABLE-TOP EQUIPMENT   

 

The equipment shall be subjected to the test magnetic field by using the induction coil of standard 
dimension (1 m x 1 m). The induction coil shall then be rotated by 90 degrees in order to expose 
the EUT to the test field with different orientations. 
FLOOR-STANDING EQUIPMENT 
The equipment shall be subjected to the test magnetic field by using induction coils of suitable 
dimensions. The test shall be repeated by moving and shifting the induction coils, in order to test 
the whole volume of the EUT for each orthogonal direction. The test shall be repeated with the coil 
shifted to different positions along the side of the EUT, in steps corresponding to 50 % of the 
shortest side of the coil. The induction coil shall then be rotated by 90 degrees in order to expose 
the EUT to the test field with different orientations.
