The IEC 61000-4-5 standard requires five applications of each polarity on the equipment.
This standard defines several acceptance criteria depending on the state of the equipment
after the test (performance still ok, degradation of the performance, damage of the
equipment).
Ethernet applications usually recommend the A criterion of IEC 61000-4-5. That is, normal
performance of the equipment after test.
The most commonly used standard to qualify Ethernet equipment against ESD is the
IEC 61000-4-2 standard.
Table 2 gives the test voltage for each test level of the standard, for both contact and air
discharge tests. Generally, Level 4 is required, i.e. the equipment has to withstand 8 kV
contact and 15 kV air discharge.
Similarly, Ethernet applications usually recommend the A criterion of IEC 61000-4-2.
