These tests are carried out according to IEC 61000-4-5, with test levels as given in Table 10 of this standard. Lower levels need not to be tested. Pulses shall be applied to the a.c. voltage wave as follows; five positive polarity pulses at the 90o phase angle, five negative polarity pulses at the 270o phase angle. Two test levels are given for different types of lighting% ^8 @# Q: Q4 |- l/ ]
