For ports where primary protection is intended, surges are applied at voltages up to 4 kv with the primary protectors fitted. Otherwise the 1 kv test level is applied without primary protection in place. Test applied to all lines simultaneously to earth (ground). Where the coupling network for the 10/700 μs waveform affects the functioning of high speed data ports, the test shall be carried out using a 1,2/50 (8/20) μs waveform and appropriate coupling network.
