This Part is Part 2 of GB/T 17626.

This Part was drafted as per the rules specified in GB/T 1.1-2009.

This Part replaced GB/T 17626.2-2006 Electromagnetic Compatibility (EMC) - Testing

and Measurement Techniques - Electrostatic Discharge Immunity Test.

Compared with GB/T 17626.2-2006, this Part has the major technical changes as

follows.

--- Increase calibration procedures and measurement uncertainty in the Scope;

--- Increase terminology. calibration, conformance test, rise time, verification;

--- Modify Clause 5.Test Levels;

--- Increase charging switch in the test generator;

--- Modify the diagram of electrostatic discharge generator;

--- Increase the characteristics and performance of the ESD generator (see 6.2);

--- Add verification of ESD setup (see 6.3);

--- Add A.8 (see Annex A);

--- Modify Annex B into Calibration of the current measurement system and

measurement of discharge current;

--- Add Annex C. Example of a calibration target meeting the requirements;

--- Add Annex D. Radiated fields from human metal discharge and ESD;

--- Add Annex E. Measurement uncertainty (MU) considerations;

--- Add Annex F. Variation in test results and escalation strategy.

This Part uses the translation method to equivalently adopt IEC 61000-4-2.2008

Electromagnetic Compatibility (EMC) - Part 4-2.Testing and Measurement

Techniques - Electrostatic Discharge Immunity Test.

The Chinese document that has a consistent correspondence with the international

documents quoted in the Normative References of this Part is as follows.

--- GB/T 2421-2008 Environmental Testing for Electric and Electronic Products -

Part 1.General and Guidance (IEC 60068-1.1988, IDT).

This Part made the following editorial changes.

--- To be consistent with the current serial standards, modify the name of this Part

into Electromagnetic Compatibility - Testing and Measurement Techniques -

Electrostatic Discharge Immunity Test.

This Part was proposed by and under the jurisdiction of National Technical Committee

for Standardization of Electromagnetic Compatibility (SAC/TC 246).

1 Scope

This Part of GB/T 17626 relates to the immunity requirements and test methods for

electrical and electronic equipment subjected to static electricity discharges, from

operators directly, and from personnel to adjacent objects. It additionally defines

ranges of test levels which relate to different environmental and installation conditions

and establishes test procedures.

2 Normative References

The following referenced documents are indispensable for the application of this

document. For dated references, only the edition cited applies. For undated references,

the latest edition of the referenced document (including any amendments) applies.

GB/T 4365-2003 Electrotechnical Terminology - Electromagnetic Compatibility

[IEC 60050(161).1990, IDT]

IEC 60068-1 Environmental Testing - Part 1.General and Guidance

3 Terms and Definitions

The following terms and definitions stipulated in GB/T 4365-2003 are applicable to this

document. For the sake of use, some terms and definitions in GB/T 4365-2003 are

repeatedly listed as follows.

4 General

This standard relates to equipment, systems, subsystems and peripherals which may

be involved in static electricity discharges owing to environmental and installation

conditions, such as low relative humidity, use of low-conductivity (artificial-fiber)

carpets, vinyl garments, etc., which may exist in all locations classified in standards

relevant to electrical and electronic equipment.

5 Test Levels

Contact discharge is the preferred test method. Air discharges shall be used where

contact discharge cannot be applied. Voltages for each test method are given in Table

1 The voltages shown are different for each method due to the differing methods of

test. This does not imply that the test severity is equivalent between test methods.
