Foreword
This document was drafted in accordance with the rules given in GB/T 1.1-2020,
Directives for standardization - Part 1: Rules for the structure and drafting of
standardizing documents.
This document is part 1 of Electromagnetic compatibility - Limits. The following parts
have been released for GB 17625:
-- Part 1: Limits for harmonic current emissions (equipment input current ≤ 16 A per
phase);
-- Part 2: Limitation of voltage changes, voltage fluctuations and flicker in public
low-voltage supply systems, for equipment with rated current ≤16 A per phase;
-- Part 3: Limitation of voltage fluctuations and flicker in low-voltage power supply
systems for equipment with rated current greater than 16 A;
-- Part 4: Assessment of emission limits for distorting loads in MV and HV power
systems;
-- Part 5: Assessment of emission limits for fluctuating loads in MV and HV power
systems;
-- Part 6: Limitation of emission of harmonic currents in low-voltage power supply
systems for equipment with rated current greater than 16 A;
-- Part 7: Limitation of voltage changes, voltage fluctuations and flicker in public
low-voltage supply systems for equipment with rated current ≤75 A and subject
to conditional connection;
-- Part 8: Limits for harmonic currents produced by equipment connected to public
low-voltage systems with input current >16 A and ≤75 A per phase;
-- Part 9: Signalling on low-voltage electrical installations - Emission levels,
frequency bands and electromagnetic disturbance levels;
-- Part 13: Assessment of emission limits for the connection of unbalanced
installations to MV, HV and EHV power systems;
-- Part 14: Assessment of emission limits for harmonics, interharmonics, voltage
fluctuations and unbalance for the connection of disturbing installations to LV
power systems;
-- Part 15: Assessment of low frequency electromagnetic immunity and emission
requirements for dispersed generation systems in LV network.
This document replaces GB 17625.1-2012 Electromagnetic compatibility - Limits -
Limits for harmonic current emissions (equipment input current ≤16 A per phase).
Compared with GB 17625.1-2012, in addition to structural adjustments and editorial
changes, the main technical changes are as follows:
a) Change the scope of application, to be consistent with GB/T 17625.8, by changing
“an input current up to and including 16 A per phase” to “a rated input current up
to and including 16 A per phase” (see Clause 1; Clause 1 of the 2012 edition);
b) Add terms and definitions of “integrated lamp” and “variable speed drive”; simply
and clarify the terminology used for “lighting equipment” (see Clause 3);
c) Classify refrigerators and freezers having one or more variable-speed drives to
Class D (see 5.1);
d) Add the classification of professional luminaires for stage lighting and studios
(see 5.2);
e) Add a description for the classification of lighting equipment (see 5.2);
f) Add a description for the classification of external power supplies (see 5.3);
g) Add requirements for the multifunction equipment (see 6.5);
h) Add a threshold of 5 W under which no emission limits apply to all lighting
equipment (see 7.1);
i) Modify the requirements applying to the dimmers when operating non-
incandescent lamps (see 7.1; Clause 7 of the 2012 edition);
j) Add a clarification for lighting equipment including one control module with an
active input power ≤ 2 W (see 7.4.1);
k) Add limit requirements for Class C equipment under different rated power (see
7.4.2 and 7.4.3);
l) Modify the emission limits for lighting equipment with a rated power ≤ 25 W (see
7.4.3; 7.3 of the 2012 edition);
m) Add compliance with this document (see Clause 8);
n) Adjust the requirements for measurement equipment to Annex A (see Annex A;
Annex B of the 2012 edition);
o) Modify the test conditions for television receiver (see B.2; C.2 of the 2012 edition);
p) Modify the test conditions for lighting equipment (see B.5 and B.6; C.5 and
C.6:2012 of the 2012 edition);
q) Remove use of reference lamps and reference ballasts for the tests of lighting
equipment (see C.5.3 and C.5.4 of the 2012 edition);
r) Add the test conditions for digital load side transmission control devices (see
B.5.5);
s) Modify the test conditions for vacuum cleaner (see B.7; C.7 of the 2012 edition);
t) Modify the test conditions for washing machine (see B.8; C.8 of the 2012 edition);
u) Modify the test conditions for induction hobs, taking also into account the other
types of cooking appliances (see B.11; C.11 of the 2012 edition);
