Interpretation of the rise-time and fall-time requirements during EUT testing in IEC
61000-4-11:2004: Electromagnetic compatibility (EMC) – Part 4-11: Testing and
measurement techniques – Voltage dips, short interruptions and voltage variations
immunity tests.
1) In IEC 61000-4-11:2004, Table 4 does not apply to EUT (equipment under test) testing.
Table 4 is for generator calibration and design only.
2) With reference to Table 1 and Table 2, there is no requirement in 61000-4-11:2004 for
rise-time and fall-time when testing EUT; therefore, it is not necessary to measure these
parameters during tests.
3) With reference to Table 4, all of the requirements apply to design and calibration of the
generator. The requirements of Table 4 only apply when the load is a non-inductive 100 Ω
resistor. The requirements of Table 4 do not apply during EUT testing.
