INTRODUCTION
Add the following new paragraph at the end of the introduction:
The limits in this standard relate to the voltage changes experienced by consumers connected
at the interface between the public supply low-voltage network and the equipment user’s
installation. Consequently, if the actual impedance of the supply at the supply terminals of
equipment connected within the equipment user’s installation exceeds the test impedance, it is
possible that supply disturbance exceeding the limits may occur.

1 Scope
Replace, in the first paragraph, “This section of IEC 1000-3” by “This part of IEC 61000”.
Throughout the text replace all references to “section” by “part”.
Replace the third paragraph by the following:
This part of IEC 61000 is applicable to electrical and electronic equipment having an input
current equal to or less than 16 A per phase, intended to be connected to public low-voltage
distribution systems of between 220 V and 250 V line to neutral at 50 Hz, and not subject to
conditional connection.
Add the following new paragraph after the third paragraph:
Equipment which does not comply with the limits of this part of IEC 61000 when tested with the
reference impedance Z of 6.4, and which therefore cannot be declared compliant with this
ref
part, may be retested or evaluated to show conformity with IEC 61000-3-11. Part 3-11 is
applicable to equipment with rated input current ≤75 A per phase and subject to conditional
connection.
Replace notes 1 and 2 by the following note:
NOTE The limits in this part of IEC 61000 are based mainly on the subjective severity of flicker imposed on the
light from 230 V/60 W coiled-coil filament lamps by fluctuations of the supply voltage. For systems with nominal
voltage less than 220 V line to neutral and/or frequency of 60 Hz, the limits and reference circuit values are under
consideration.

IEC 60868 will be withdrawn and replaced by IEC 61000-4-15 in 2003. Flickermeters complying with IEC 61000-4-15
may also be used for flicker measurements associated with this part of IEC 61000-3.

3 Definitions
Replace the following existing definitions as follows:
3.1
r.m.s. voltage shape
U(t)
the time function of r.m.s. voltage, evaluated as a single value for each successive half period
between zero-crossings of the source voltage (see figure 2)
3.2
voltage change characteristic
ΔU(t)
the time function of the r.m.s. voltage change evaluated as a single value for each successive
half period between zero-crossings of the source voltage between time intervals in which the
voltage is in a steady-state condition for at least 1 s (see figure 2)
NOTE Since this characteristic is only used for assessments using calculations, the voltage in the steady-state
condition is assumed to be constant within the measurement accuracy (see 6.2).
3.3
maximum voltage change characteristic
ΔU
max
the difference between maximum and minimum r.m.s. values of a voltage change characteristic
(see figure 2)
---------------------- Page: 8 ----------------------
61000-3-3 Amend. 1 IEC:2001 – 9 –
3.5
voltage fluctuation
series of changes of r.m.s. voltage evaluated as a single value for each successive half-period
between zero-crossings of the source voltage
3.10
flicker impression time
t
f
value with a time dimension which describes the flicker impression of a voltage change
characteristic
Add, on page 15, the following new definitions:
3.11
conditional connection
connection of equipment requiring the user’s supply at the interface point to have an
impedance lower than the reference impedance Z in order that the equipment emissions
ref
comply with the limits in this part.
NOTE Meeting the voltage change limits may not be the only condition for connection; emission limits for other
phenomena such as harmonics, may also have to be satisfied.
3.12
interface point
interface between a public supply network and a user’s installation

4 Assessment of voltage fluctuations and flicker
Replace the existing title by the following new title:

4.1 Assessment of voltage fluctuations and flicker
Replace "waveform" in the first sentence by "characteristic".
Replace the first line of note 3 by the following:
3 For single-phase and symmetrical three-phase equipment the voltage change can, provided X is positive
(inductive), be approximated to:
Replace “waveform” by “characteristic” and “waveforms” by “characteristics” specifically in
subclauses 4.2.2, 4.2.3, 4.2.3.1, 4.2.3.2 and in table 1.

Replace the existing second paragraph as follows:
The relative voltage change characteristic shall be obtained from a histogram of U(t) (see
figure 3).

Replace the existing text of the clause by the following new text:
The limits shall be applicable to voltage fluctuations and flicker at the supply terminals of the
equipment under test, measured or calculated according to clause 4 under test conditions
described in clause 6 and annex A. Tests made to prove compliance with the limits are
considered to be type tests.
The following limits apply:
– the value of P shall not be greater than 1,0;

– the value of P shall not be greater than 0,65;
lt
– the value of d(t) during a voltage change shall not exceed 3,3 % for more than 500 ms;
