1 INTRODUCTION
2 (For information of the NC's only, not to be part of the standard)
3 Amendment 2 to IEC 61000-3-2 Ed. 5.1 (= IEC 61000-3-2:2018 plus IEC 61000-3-2/AMD1:2021)
4 is based on 77A/1098/Q, 77A/1106/DISH, 77A/1123A/RQ, 77A/1149/CD, 77A/1150/CD,
5 77A/1151/CD, 77A/1152/CD, the observations to these CD’s and discussions in SC77A / WG1
6 during the meetings October 2021, May 2022 and November 2022.
7 At CD stage the amendment has been split into 4 different fragments:
8 Fragment 1 Lighting equipment
9 Fragment 2 Test conditions
10 Fragment 3 Repeatability and measurement uncertainty
11 Fragment 4 Miscellaneous
12 As the number of comments on the 4 different CDs was not very high, SC77A WG1 during its
13 meeting November 2022 in San Diego decided to combine the 4 fragments already at CDV stage.
14 The CDV contains the following main changes in comparison with IEC 61000-3-2 ED 5.1:
15 • Inclusion of Interpretation Sheet IEC 61000-3-2/AMD1/ISH1 ED5
16 • New terms and definitions reflecting the actual luminaires on the market
17 • Adapted test conditions for actual luminaires on the market
18 • Consolidate the test conditions for video-cassette recorders
19 • Revision of test conditions for washing machines
20 • Clarification of references in clause B.17
21 • Adding IEC Guide 115 to the normative references
22 • Better specification for repeatability
23 • New specification for measurement uncertainty and decision rule
24 • Adding IEC TR 61000-1-6:2012/COR1:2014 to the bibliography
25 • New definition for an independent function
26 • New definitions for symmetrical control, asymmetrical control and phase control
27 • Clarification that special test conditions in Annex B have precedence over the general
28 test conditions in clause 6.3.1
29 • Clarification for the calculation of THC, THD or POHC (The disregarding of currents less
30 than 0,6 % of input current or less than 5 mA applies only to individual harmonics.)
31 • Clarification for the application of class D limits
32 • Clarification for the requirements on the test voltage in A.2, bullet d)
33 • Addition of an informative Annex D “Symmetry of mains current waveforms”
34

125 6.3.3 General requirements
126 Change the headline to read:
127 6.3.3 General requirements and recommendations
128
129 6.3.3.1 Repeatability
130 Change the complete text of clause 6.3.3.1 into the following:
131 The repeatability (see 3.15) of the average value for the individual harmonic currents of an order
132 ≤ 11 over the entire test observation period should be better than (5 % of the applicable limit +
133 1mA), when the following conditions are met:
134 − the same equipment under test (EUT) (not another of the same type, but the exact same
135 specimen);
136 − the same test system;
137 − the same location;
138 − identical test conditions;
139 − identical climatic conditions, if relevant.
140 The repeatability of the average value of individual harmonic currents of an order > 11 under the
141 same conditions should be better than (10 % of the applicable limit + 1 mA).
142 This repeatability recommendation can serve the purpose of assisting in the determination of the
143 necessary test observation period when this period is not fixed by Table 4 nor Annex B. However,
144 in no case does this recommendation serve as a pass/fail criterion for the assessment of
145 compliance with the requirements of this document.
146 For the avoidance of doubt, in cases where all relevant limits are met, the test results shall be
147 accepted as demonstrating compliance, even if the repeatability values exceed the
148 recommended values in this clause.
149 6.3.3.4 Application of limits
150 Replace the third paragraph with the following text:
151 Harmonic currents less than 0,6 % of the average input current measured under the test
152 conditions, or less than 5 mA, whichever is greater, are disregarded. This exclusion applies only
153 to the comparison of individual harmonic currents against limits.
154 6.5 Multifunction equipment
155 Delete Note 1 and remove the number from Note 2.
156 Replace the third paragraph with the following text:
157 For equipment for which it is not obvious how to operate each function alone, instructions may
158 be provided for testing purposes explaining how the function can be operated alone. These
159 instructions may specify internal changes in the equipment, exclusively for the purpose of
160 operating independent functions alone during the test. The equipment shall be tested
161 accordingly. The test report shall contain a detailed description of how the separate testing of
162 independent functions has been achieved and how the tests have been performed.
163
164 7.4.3 Rated power ≥ 5 W and ≤ 25 W
165 Add the following text and the note at the end of the second dash:
166 If the waveform includes a noise-like component that makes it difficult to determine the phase angles
167 with some instruments intended to comply with IEC 61000-4-7, an oscilloscope or any other time-
168 domain measurement may be used, if it meets the same bandwidth limitation requirement. This can, for
169 example, be achieved by filtering and/or data acquisition combined with FFT/IFFT operations.
