3 Foreword All technical content of this Part of GB is mandatory. GB "Electromagnetic compatibility - limits" now includes the following parts: GB Electromagnetic compatibility limits Limits for harmonic current emissions ( equipment input current 16A per phase) GB Electromagnetic compatibility (EMC). Limits. Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems, for equipment with rated current 16A per phase and not subject to conditional connection GB/Z Electromagnetic compatibility Limits - Limitation of voltage fluctuations and flicker in low-voltage power supply systems for equipment with rated current greater than 16A GB/Z Electromagnetic compatibility Limits - Assessment of emission limits for distorting loads in MV and HV power systems GB/Z Electromagnetic compatibility - Limits - Assessment of emission limits for fluctuating loads in MV and HV power systems GB/Z Electromagnetic compatibility Limits - Limitation of emission of harmonic currents in low-voltage power supply systems for equipment with rated current greater than 16A This Part is Part 1 of GB This Part was drafted in accordance with rules given in GB/T This Part replaces GB Electromagnetic compatibility limits Limits for harmonic current emissions ( equipment input current 16A per phase). Compared with GB , in addition to editorial changes, the major technical changes of this Part are as follows: - DELETE citations of GB and GB ADD citations of IEC : 1985, IEC and ITU-R BT Recommendation (see Chapter 2); - DELETE the definitions for "semi-lamps" and "lighting device". ADD definitions for "total harmonic", "total harmonic distortion", "repeatability of measurements", Page 3 of 41

4 "reproducibility of results of measurements", and "variability of results of measurements" (see Chapter 3); - ADD conditions and requirements of allowing to use simplified test method (see Chapter 6); - MODIFY the instructions related to harmonic current measurement power values (see 6.2.2); - ADD the harmonic current measurement repeatability and reproducibility requirements (see and ); - ADD application requirements for harmonic current limits (see ); - ADD diagrams to describe relative phase angle and current parameters in 7.3b) (see 7.3 Table 2); - MODIFY the harmonic current limit requirements of discharge lamp of which the active power is not more than 25 W in C class devices (see 7.3b)); - ADD a note to the harmonic current measurement circuit for single-phase and three-phase equipment (see Figure A.1 and Figure A.2); - ADD the requirements of measurement conditions for television receiver (see C.2.2); - ADD input signal and load requirements for the test conditions of other audio amplifier (see C.3); - MODIFY the requirements for lamp test conditions (see C.5.2); - MODIFY the requirements for vacuum cleaner test conditions (see C.7); - MODIFY the requirements for washing machine test conditions (see C.8); - MODIFY the requirements for IT equipment test conditions (see C.10); - DELETE the requirements for other equipment test conditions. This Part is equivalent to international standard IEC : Cor.1 (Version 3.2) Electromagnetic compatibility (EMC) Part 3-2: limits Limits for harmonic current emissions ( equipment input current 16A per phase). The technical corrigendum content of the international standard has been included in this Part and is indicated with double-vertical lines (II) at the margin of relevant articles. The national documents, which have consistency corresponding relation with those international documents cited by normative references of this Part, are as follows: Page 4 of 41
