The Basic EMC Standards for Surge define the methods of generating consistently reproducible surge voltages for test purposes. They specify generator and coupler/decoupler design and performance in sufficient detail to produce correlatable results between test sites.
While the Basic EMC Standard specifies how to perform Surge testing, the Generic, Product and Product Family Standards specify the test levels and pass/fail performance criteria.
IEC 61000-4-5 also includes climatic specification as follows:
Ambient temperature :
15°C to
35°C
Relative Humidity :
10% to 75%
Atmospheric Pressure :
86kPa (860 mbar)
to 106kPa (1060 mbar)
Other values may be specified in the test specification.
The surge test can be destructive to the EUT if adequate protection is not incorporated into the design. Therefore, this test should be carried out only after a successful burst ( EFT ) test.
The test level is set by the IEC / EN as a function of use and exposure class.

For each coupling path 5 pulses positive and 5 pulses negative at each 0°, 90°, 180°
and 270° are applied.
All lower levels including the selected test level are tested.
