IEC and EN standards cover testing of 3 phase AC and DC power ports. They include recommendations for the coupling and decoupling component values within the CDN. These values are largely based on the European model for AC power lines.

FP-SURGE 100M2 includes all the IEC and EN requirements with manual coupling path switching. FP-SURGE 100M2 EUT output has specially designed HV terminals, which provide enhanced personnel safety in relation to the high voltage impulse. In December 2005 the IEC 61000-4-5 Edition 2 was approved. This new edition 2 defines the maximum voltage drop due to the decoupling inductors. This requires different decoupling inductors dependant on the EUT current.

The higher the current the lower the inductance must be. The FP-SURGE 100M2 is compliant to the edition 2. The ANSI standards C62.41 and C62.45 contains much the same information as the IEC but based around the American experience with AC power lines. No requirements about voltage drop across the decoupling inductors are included.
