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); v) Modify the test conditions for arc welding equipment (see B.14; C.14 of the 2012 edition); w) Add the test conditions for high pressure cleaner (see B.15); x) Add the test conditions for refrigerators and freezers (see B.16); y) Add the test conditions for external power supplies (see B.17); z) Add the normative reference of partial odd harmonic current (see Annex C). This document modifies and adopts IEC 61000-3-2.2020 Electromagnetic compatibility (EMC) - Part 3-2.Limits - Limits for harmonic current emissions (equipment input current ≤16 A per phase). The technical differences between this document and IEC 61000-3-2.2020 and the reasons are as follows. -- For “professional equipment” (see 3.9) in “terms and definitions”, adopt the definition in GB/T 4365-2003 Electrotechnical terminology - Electromagnetic compatibility; -- Delete “60 Hz”, “230/400 V and 240/415 V” in “General” (see 6.1), because neither the frequency 60 Hz, nor is the voltage level “230/400 V and 240/415 V” used in China, so the relevant parameter of 60 Hz and the voltage parameters of “230/400 V and 240/415 V” are removed; -- Add a situation without default conditions (see Annex B.2.2.2) in the part “television receiver” of “type test”, to improve the operability of the test; -- Use the normative reference GB/T 20550-2013 to replace IEC 60155.1993 in the part “luminaire” of “type test” (see Annex B.5.3); -- Remove “subject to approval by National Committees” in “General” of “POHC calculation” (see Annex C.1). The following editorial changes have been made for this document. -- Change the standard name to “Electromagnetic compatibility - Limits - Part 1. Limits for harmonic current emissions (equipment input current≤16 A per phase)” to be consistent with the standard system in China; -- Use GB/T 17626.7 to replace the informative reference IEC 61000-4-7 in Note 2 of C.1 of Annex C, and add it to the references.
