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.

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.

lambda 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).

lambda 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.

lambda 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.

lambda 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).

lambda 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.

lambda 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.

lambda 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.

lambda 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)
