This part is identical with international standard IEC 61000-4-4:2012 Electromagnetic Compatibility (EMC) — Part 4-4: Testing and Measurement Techniques — Electrical Fast Transient/Burstimmunity Test. For the purposes of this part, the following editorial changes have also been made: — In order to be consistent with the existing standard series, the name of this part is changed to Electromagnetic Compatibility — Testing and Measurement Techniques — Electrical Fast Transient/Burstimmunity Test. This part was proposed by and is under the jurisdiction of the National Technical Committee 246 on Electromagnetic Compatibility of Standardization Administration of China (SAC/TC 246). The previous editions of this part are as follows: GB/T 17626.4-1998, GB/T 17626.4-2008. Electromagnetic Compatibility — Testing and Measurement Techniques — Electrical Fast Transient/Burstimmunity Test 1 Scope This part of GB/T 17626 relates to the immunity of electrical and electronic equipment to repetitive electrical fast transients. It gives immunity requirements and test procedures related to electrical fast transients/bursts. It additionally defines ranges of test levels and establishes test procedures. The object of this standard is to establish a common and reproducible reference in order to evaluate the immunity of electrical and electronic equipment when subjected to electrical fast transient/bursts on supply, signal, control and earth ports. The test method documented in this part describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon. Note: As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC. As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test standard is applied or not, and if applied, they are responsible for determining the appropriate test levels and performance criteria. SAC/TC 246 and its subcommittees are prepared to co-operate with product committees in the evaluation of the value of particular immunity tests for their products. This part specifies: — test voltage waveform; — range of test levels; — test equipment; — calibration and verification procedures of test equipment; — test setups; — test procedure. This part gives specifications for laboratory and in situ tests. 2 Normative References The following referenced documents are indispensable for the application of this document.

Significant for the test are the high amplitude, the short rise time, the high repetition frequency, and the low energy of the transients. The test is intended to demonstrate the immunity of electrical and electronic equipment when subjected to types of transient disturbances such as those originating from switching transients (interruption of inductive loads, relay contact bounce, etc.). 5 Test Levels The preferred test levels for the electrical fast transient test, applicable to power, control, signal and earth ports of the equipment are given in Table 1.   Table 1 Test Levels Open circuit output test voltage and repetition frequency of the impulses Level Power ports, earth port (PE) Signal and control ports Voltage peak kV Repetition frequency kHz Voltage peak kV Repetition frequency kHz 1 0.5 5 or 100 0.25 5 or 100 2 1 5 or 100 0.5 5 or 100 3 2 5 or 100 1 5 or 100 4 4 5 or 100 2 5 or 100 X a Special Special Special Special The use of 5 kHz repetition frequency is traditional, however, 100 kHz is closer to reality. Product committees should determine which frequencies are relevant for specific products or product types. With some products, there may be no clear distinction between power ports and signal ports, in which case it is up to product committees to make this determination for test purposes. a "X" can be any level, above, below or in between the others. The level shall be specified in the dedicated equipment specification. For selection of test levels, see Annex B. 6 Test Equipment 6.1 Overview The calibration procedures of 6.2.3, 6.3.2 and 6.4.2 ensure the correct operation of the test generator, coupling/decoupling networks, and other items making up the test setup so that the intended waveform is delivered to the EUT. 6.2 Burst Generator 6.2.1 General The simplified circuit diagram of the generator is given in Figure 1. The circuit elements Cc, Rs, Rm, and Cd are selected so that the generator delivers a fast transient under open circuit conditions and with a 50 Ω resistive load. The effective output impedance of the generator shall be 50 Ω.

This part was proposed by and is under the jurisdiction of the National Technical Committee 246 on Electromagnetic Compatibility of Standardization Administration of China (SAC/TC 246). The previous editions of this part are as follows: GB/T 17626.4-1998, GB/T 17626.4-2008. Electromagnetic Compatibility — Testing and Measurement Techniques — Electrical Fast Transient/Burstimmunity Test 1 Scope This part of GB/T 17626 relates to the immunity of electrical and electronic equipment to repetitive electrical fast transients. It gives immunity requirements and test procedures related to electrical fast transients/bursts. It additionally defines ranges of test levels and establishes test procedures. The object of this standard is to establish a common and reproducible reference in order to evaluate the immunity of electrical and electronic equipment when subjected to electrical fast transient/bursts on supply, signal, control and earth ports. The test method documented in this part describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon. Note: As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC. As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test standard is applied or not, and if applied, they are responsible for determining the appropriate test levels and performance criteria. SAC/TC 246 and its subcommittees are prepared to co-operate with product committees in the evaluation of the value of particular immunity tests for their products. This part specifies: — test voltage waveform; — range of test levels; — test equipment; — calibration and verification procedures of test equipment; — test setups; — test procedure. This part gives specifications for laboratory and in situ tests. 2 Normative References The following referenced documents are indispensable for the application of this document.

Significant for the test are the high amplitude, the short rise time, the high repetition frequency, and the low energy of the transients. The test is intended to demonstrate the immunity of electrical and electronic equipment when subjected to types of transient disturbances such as those originating from switching transients (interruption of inductive loads, relay contact bounce, etc.). 5 Test Levels The preferred test levels for the electrical fast transient test, applicable to power, control, signal and earth ports of the equipment are given in Table 1.   Table 1 Test Levels Open circuit output test voltage and repetition frequency of the impulses Level Power ports, earth port (PE) Signal and control ports Voltage peak kV Repetition frequency kHz Voltage peak kV Repetition frequency kHz 1 0.5 5 or 100 0.25 5 or 100 2 1 5 or 100 0.5 5 or 100 3 2 5 or 100 1 5 or 100 4 4 5 or 100 2 5 or 100 X a Special Special Special Special The use of 5 kHz repetition frequency is traditional, however, 100 kHz is closer to reality. Product committees should determine which frequencies are relevant for specific products or product types. With some products, there may be no clear distinction between power ports and signal ports, in which case it is up to product committees to make this determination for test purposes. a "X" can be any level, above, below or in between the others. The level shall be specified in the dedicated equipment specification. For selection of test levels, see Annex B. 6 Test Equipment 6.1 Overview The calibration procedures of 6.2.3, 6.3.2 and 6.4.2 ensure the correct operation of the test generator, coupling/decoupling networks, and other items making up the test setup so that the intended waveform is delivered to the EUT. 6.2 Burst Generator 6.2.1 General The simplified circuit diagram of the generator is given in Figure 1. The circuit elements Cc, Rs, Rm, and Cd are selected so that the generator delivers a fast transient under open circuit conditions and with a 50 Ω resistive load. The effective output impedance of the generator shall be 50 Ω.
