Test 2.1.1 does not apply when the equipment is designed to always be used with primary protection and the operator agrees. If this test is not performed, the appropriate test from Table 7 applies.
If the inherent protection of the port under test contains surge protective devices (SPDs) that are connected to a protective earth (PE), a Uc(max) of 1.5 kV shall be used instead of 6 kV.
If the equipment has an insulated case, the 6 kV test is applied with the equipment wrapped in conductive foil and the foil is connected to the generator return.
When the equipment contains high current- carrying components that eliminate the need for primary protection, this test does not apply.
(Lower voltage level testing also required for each test – see clause 7.3 of
[ITU-T K.44].)

NOTE 1 – The test conditions for Test 2.2.2 (basic test level) may be adapted to the local conditions, by variation of the test parameters within the following limits, so that
I2t = 1 A2s is fulfilled:
Ua.c.(max) = 300 V... 600 V, selected to meet local conditions;
t £ 1.0 s, selected to meet local conditions;
R £ 600 Ω, is to be calculated according to Equation 6-2:
R = Ua.c.(max)√t (6-2)
NOTE 2 – For Test 2.2.2 (enhanced test level), the equipment shall comply with the specified criterion for all voltage–duration combinations bounded (on and below) by the 10 A2s voltage–duration curve in Figure 1. The curve in Figure 1 is defined by Equation 6-1 and the boundary conditions in this table.
NOTE 3 – The a.c. mains voltage and frequency for Test 2.3.1 may be changed to the local mains supply voltage and frequency values. For a.c. test voltage values other than 230 V, the test resistor values should be adjusted to provide the same prospective short-circuit current values that occur in the 230 V test condition.
t: duration; Ua.c.: alternating current voltage; Ua.c.(max): maximum alternating current voltage; Wsp(max) maximum specific energy; f: frequency
