12.2 Routine withstand voltage test
Replace the text of the third paragraph with the following new text:
During the routine testing of quantity produced machines up to 200 kW (or kVA) and rated for
U ≤ 1 kV, the 1 min test may be replaced by a test of 1 s (see IEC 60034-1) at 120 % of the
N
test voltage specified in Table D.1, for example S – (manufacturer specified): (TVF · 2U +
N
1 kV ) · 1,2.
Table D.1 – Withstand test voltages according to IVIC for Type I insulation systems
