This Part is Part 1 of GB/T 17626.
This Part equivalently adopts IEC 61000-4-1(2000) Electromagnetic compatibility (EMC) –
Part 4: Testing and measurement techniques – Part 1: Overview of immune tests. This Part
gives practical guidance on test and measurement techniques and provides general advice on
the selection of relevant tests.
This Part replaced GB/T 17626.1-1998 Electromagnetic compatibility - Testing and
measurement techniques - Overview of immunity tests since the date of implementation.
Compared with GB/T 17626.1-1998, the major changes of this Part are as follows:
--- Delete Clause 6 Environmental Conditions, Clause 8 Selection of Severity Levels, and
Clause 9 Evaluation of Test Results;
--- Delete Appendix A brief description of the immunity test and Appendix B the
characteristics of the conducted transient test;
--- Add Table 1 select the immunity test according to the installation location (environment);
--- Add Table 2 scope of application of the immunity test based on the EUT port.
This Part was proposed by China Electricity Council.
This Part shall be under the jurisdiction of National Technical Committee on Electromagnetic
Compatibility of Standardization Administration of China (SAC/TC 246).

Electromagnetic Compatibility – Testing and Measurement
Techniques – Overview of immunity Tests
1 Scope
This Part covers testing and measuring techniques for electric and electronic equipment
(apparatus and systems) in its electromagnetic environment.
The object of this Part is to give applicability assistance to the technical committees of IEC or
other bodies, users and manufacturers of electrical and electronic equipment on EMC standards
within the GB/T 17626 series on testing and measurement techniques and to provide general
recommendations concerning the choice of relevant tests.

interpretation of fundamental definitions and terms (idt IEC 61000-1-1:1992)

emissions (equipment input current≤16A per phase) (IEC 61000-3-2:2001, IDT)
GB 17625.2-1999 Electromagnetic compatibility - limits - Limitation of voltage
fluctuations and flicker in low-voltage supply systems for equipment with rated
current≤16A (idt IEC 61000-3-3:1994)
GB/Z 17625.3-2000 Electromagnetic compatibility – Limits - Limitation of voltage
fluctuations and flicker in low-voltage power supply systems for equipment with rated
current greater than 16A (idt IEC 61000-3-5:1994)
GB/Z 17625.6-2003 Electromagnetic compatibility – Limits - Limitation of emission of
In general, this test should be limited to products which are susceptible to magnetic fields (for
example Hall effect devices, CRT and special products to be installed in high magnetic field
environments). Exclusions include equipment which is intended for use in a low magnetic field
environment.
Test according to GB/T 17626.9 (Pulse magnetic field immunity test)
This test is mainly applicable to products to be installed in electrical plants (for example
telecontrol centers in close proximity to switchgear).
Test according to GB/T 17626.10 (Damped oscillatory magnetic field immunity test)
This test is mainly applicable to products to be installed in high-voltage substations.
Test according to GB/T 17626.11 (Voltage dips, short interruptions and voltage
variations immunity test)
This test is applicable to equipment with a rated input current of less than 16 A per phase,
connected to a.c. mains.
Test according to GB/T 17626.12 (Oscillatory wave immunity test)
The ring wave test is applicable to equipment connected to a.c. mains in certain countries (for
example the mains network in the USA). The damped oscillatory wave test is applicable to
equipment used in power plants and high-voltage substations (for example static relays).
Test according to GB/T 17626.13 (Harmonics, interharmonics including mains
signalling at a.c. power port, low-frequency immunity tests)
This test may be applied to equipment sensitive to precise zero crossing in time on the a.c.
mains or to specific harmonic components.
Test according to GB/T 17626.14 (Voltage fluctuation immunity test)
In general, voltage fluctuations have an amplitude not exceeding 10 %; therefore, most
equipment is not disturbed by voltage fluctuations. However, this test may be applicable to
equipment intended to be installed at locations where the mains have larger fluctuations.
Test according to GB/T 17626.15 (Flickermeter – Functional and design specifications)
This is a specification for a flickermeter, intended to indicate correct flicker perception level
for all practical voltage fluctuation waveforms, especially with regard to the emission
requirements according to GB 17625.2, GB/Z 17625.3 and IEC 61000-3-11.
Test according to IEC 61000-4-16:1999 (Test for immunity to conducted, common mode
disturbances in the frequency range 0 Hz to 150 kHz)
