_____________
Main title
Replace the part title on the cover page, the title page, above the Foreword and the Scope by
the following:
Part 4-34: Testing and measurement techniques –
Voltage dips, short interruptions and voltage variations immunity tests
for equipment with mains current more than 16 A per phase
1 Scope
Replace the entire second paragraph of the scope by the following:
This standard applies to electrical and electronic equipment having a rated mains current
exceeding 16 A per phase. (See Annex E for guidance on electrical and electronic equipment
rated at more than 200 A per phase.) It covers equipment installed in residential areas as well
as industrial machinery, specifically voltage dips and short interruptions for equipment
connected to either 50 Hz or 60 Hz a.c. networks, including 1-phase and 3-phase mains.
NOTE 1 Equipment with a rated mains current of 16 A or less per phase is covered by publication IEC 61000-4-11.
NOTE 2 There is no upper limit on rated mains current in this publication. However, in some countries, the rated
mains current may be limited to some upper value, for example 75 A or 250 A, because of mandatory safety
standards.
3.6 rated input voltage
Delete this term and definition and renumber the following terms and definitions accordingly.

Modify the first sentence as follows:
The voltages in this standard use the rated voltage for the equipment as a basis for voltage
test level specification (U ).

5.1 Voltage dips and short interruptions
Delete the last two paragraphs before Table 1, beginning with “Shorter durations in the
table…”, and ending with “…after the voltage dip.”
Table 1 – Preferred test level and durations for voltage dips
Replace the existing Table 1 by the following new Table 1:

b
To be defined by product committee. For equipment connected directly or indirectly to public network, the levels
must not be less severe than class 2.
c
"25/30 cycles" means "25 cycles for 50 Hz test" and "30 cycles for 60 Hz test", “10/12 cycles” means “10 cycles
for 50 Hz test” and “12 cycles for 60 Hz test” and “250/300 cycles” means “250 cycles for 50 Hz test” and “300
cycles for 60 Hz test”.
d
May be replaced by product committee with a test level of 50 % for equipment that is intended primarily for
200 V or 208 V nominal operation.

5.2 Voltage variations (optional)
Add the following paragraph immediately below Table 3:
For voltage variations in three-phase systems with or without neutral, all the three phases
shall be tested simultaneously. Simultaneous voltage variations in three-phase systems are
positioned at the zero-crossing of one of the voltages.
