AC Power Fault Test is that the EUT may be damaged, but it may not become a fire,
fragmentation, or electrical safety hazard. Passing criteria for the Current Limiter Test is that
the EUT may be damaged but it may not exceed the acceptable time/current criteria (that is,
cannot cause the wiring simulator as shown in Figure 4.2 to open) nor become a fire,
fragmentation, or electrical safety hazard.
The indicator used in measuring fire, fragmentation, and electrical safety hazards is a
bleached, untreated cotton cheesecloth wrapped around the EUT. Compliance with testing
is determined by the absence of ignition, charring, and the ejection of molten material or
fragments.
First Level Lightning Surge Test
To pass the First Level Lightning Surge Test, the EUT must be undamaged and continue to
operate properly after the stress is applied. This is referred to as passing “operationally.”
Table 4.3 presents the conditions for the First Level inter-building criteria. Applicants have
the option to submit their equipment to meet surges 1, 2, 4, and 5 or surges 3, 4, and 5.
Table 4.4 presents the conditions for the intra-building criteria.
Notes:
1. Primary protectors are removed for all tests.
2. For EUT containing secondary voltage limiting and current limiting protectors, tests are to be performed at the indicated voltage(s)
and repeated at a reduced voltage and current just below the operating threshold of the secondary protectors.
3. Test 1 and 2 can be replaced with Test 3 or vice versa.
4. Alternatively, a surge generator of 1.2x50 μs open-circuit voltage waveform (8x20 μs short-circuit current waveform) per
IEEE C62.41 may be used. The current shall be limited by the inclusion of a series 3
generator.
5. This test is to be performed on up to 12 Tip and Ring pairs simultaneously.

Test 2, placed externally to the surge generator.
