This document replaces GB/T 17799.2-2003 "Electromagnetic compatibility - Generic

standards - Immunity for industrial environments". Compared with GB/T 17799.2-2003,

in addition to structural adjustments and editorial changes, the main technical changes

are as follows.

a) Modify the environmental description in the scope (see Chapter 1 of this Edition;

Chapter 1 of Edition 2003);

b) Modify normative references (see Chapter 2 of this Edition; Chapter 2 of Edition

2003);

c) Modify the terms and definitions such as "port" and "signal/control port". Add the

terms and definitions such as "long distance line", "DC distribution network",

"industrial location", "electromagnetic environment" and "public mains network

" (see Chapter 3 of this Edition; Chapter 3 of Edition 2003);

d) Add measurement uncertainty requirements (see Chapter 8 of this Edition);

e) Modify the frequency range of the RF electromagnetic field radiated immunity

test (see Chapter 9 of this Edition; Table 1 of Edition 2003);

f) Modify the test levels and notes for surge (impact) immunity test (see Chapter 9

of this Edition; Tables 2~4 of Edition 2003);

g) Modify the repetition frequency of the electrical fast transient burst immunity test

(see Chapter 9 of this Edition; Tables 2~4 of Edition 2003);

h) Add the IEC 61000-4-34 basic standard. Changed the requirements for voltage

sag and voltage interruption immunity tests (see Chapter 9 of this Edition; Table

4 of Edition 2003);

i) Delete the immunity test requirements for the functional earth port (see Chapter 8

of Edition 2003);

j) Add an informative appendix on the guidelines for product standardization

technical committees (see Annex A of this Edition);

k) Add Bibliography (see Bibliography of this Edition).

This document is modified by adopting IEC 61000-6-2.2016 "Electromagnetic

compatibility (EMC) - Part 6-2.Generic standards - Immunity standard for industrial

environments".

The technical differences between this document and IEC 61000-6-2.2016 and their

reasons are as follows.

- Add the requirement that "For tests where there are multiple test methods to choose

from, the original test method shall be used for retesting" (see Chapter 9);

- Delete the parameters related to 60 Hz in Tables 1 and 4, including the 60 Hz

frequency point and notes of 1.1 power frequency magnetic field in Table 1, and

the requirements and footnote e of 4.2 voltage sag and 4.3 voltage interruption

duration of 12 cycles, 30 cycles and 300 cycles in Table 4, to apply to China's

national conditions (see Chapter 9);

- Add footnote g to "Line-to-ground" in 2.2 Surge (impact) in Table 2 to clarify the

requirement to use "all lines-to-ground" for symmetrical interconnection lines

(see Chapter 9);

- As IEC 61000-4-31 has been published, the footnote a of Table A.1 in Annex A,

"This basic standard is currently under development", has been deleted. The test

level of broadband disturbance is noted as "to be determined" (see Annex A). The

footnote 1 of IEC 61000-4-31 in the reference, "under consideration", has been

deleted (see Bibliography).

The following editorial changes were made to this document.

- To be consistent with the Chinese standard system, the name of the standard was

changed to "Electromagnetic compatibility - Generic standards - Part 2.Immunity

standard for industrial environments";

- Corrected the editorial error in IEC 61000-6-2.2016, and changed the second

"Table 4" in footnote d of Table 3 to "this table";

- Added "No." to the table header corresponding to each test number column in

Tables 1 to 4.

Attention is drawn to the possibility that some of the elements of this document may be

the subject of patent rights. The issuing authority shall not be held responsible for

identifying any or all such patent rights.

This document was proposed by and shall be under the jurisdiction of National

Technical Committee on Electromagnetic Compatibility of Standardization

Administration of China (SAC/TC 246).

1 Scope

The electromagnetic compatibility (EMC) immunity requirements of this document

apply to the following electrical and electronic device used in industrial locations,

covering the frequency range of 0 Hz~400 GHz. No testing is required at frequencies

where no immunity requirements are specified.

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 17626.21-2014, Electromagnetic compatibility - Testing and measurement

techniques-Reverberation chamber test methods (IEC 61000-4-21.2011, IDT)

3 Terms and definitions

For the purposes of this document, the terms and definitions defined in IEC 60050-161

as well as the followings apply.

A port to which the wires or cables are connected to the device to transmit the

input/output electrical energy required for operation.

4 Performance criteria

The functional description and specific performance criteria definitions of the device

under test (EUT) during or after the immunity test shall be provided by the manufacturer

and recorded in the test report.

5 Test conditions

The EUT shall be tested in the most sensitive operating mode expected (e.g., determined

by limited pre-testing). This mode shall correspond to normal use. The configuration of

the test specimen shall be varied to obtain maximum sensitivity under conditions

consistent with typical applications and actual installations.

If the device has many similar ports, or many ports have similar connections, a

sufficient number of ports shall be selected to simulate actual working conditions,

ensuring that all different types of terminals are included.

6 Product documentation

If the manufacturer wants to use its own technical specifications to assess the acceptable

level of EMC performance or the degradation of EMC performance of the device during

or after the tests required by this document, this shall be stated in the user

documentation.

7 Applicability

The application of immunity evaluation tests depends on the specific device and its

configuration, ports, technology and operating conditions.

The relevant ports of the device shall be tested according to Tables 1~4.The test shall

be performed only when the relevant ports exist.

8 Measurement uncertainty

If guidance for the evaluation of instrumental uncertainty for immunity tests is specified

in IEC/TR61000-1-6 or an equivalent basic standard, that guidance shall be followed.

9 Immunity test requirements

The device immunity test requirements covered in this document are given port by port

and listed in Tables 1~4.
