environments (GB/T 17799.2);
- Electromagnetic compatibility - Generic Standards - Emission Standard for
residential, commercial and light-industrial environments (GB 17799.3);
- Electromagnetic compatibility - Generic Standards - Emission Standard for
industrial environments (GB 17799.4);
- Electromagnetic compatibility - Generic standards - HEMP immunity for indoor
device (GB/T 17799.5);
- Electromagnetic compatibility - Generic standards - Immunity for power station
and substation environments (GB/Z 17799.6);
- Electromagnetic compatibility - Generic standards - Part 7: Immunity requirements
for device intended to perform functions in a safety-related system (functional
safety) in industrial locations (GB/T 17799.7).
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).
Electromagnetic compatibility - Generic standards - Part 2:
Immunity standard for industrial environments
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.
If there is no relevant specific product or product class EMC immunity standard, this
generic EMC immunity standard applies.
This document applies to electrical and electronic device operated in industrial
locations (as defined in 3.7), including both indoor and outdoor locations.
This document also applies to device directly connected to a direct current (DC)
distribution network or battery-powered and intended for use in industrial locations.
This document specifies immunity test requirements related to continuous and transient,
conducted and radiated disturbances, and electrostatic discharge for device within its
scope.
This document selects the immunity requirements to ensure that the device working in
industrial locations has an appropriate immunity level. However, these immunity levels
do not cover some extreme situations that may occur in any location with a very low
probability. The tests recommended in this document do not include all disturbance
phenomena, only those related to the device covered by this document. These test
requirements represent the basic EMC immunity requirements. This document specifies
the test requirements for each port considered.
NOTE 1: Information on other disturbance phenomena is given in IEC/TR 61000-4-1.
NOTE 2: This document does not include safety considerations.
NOTE 3: In some special cases, disturbance levels exceeding the test levels specified in this
document may occur. For example, device installed close to industrial, scientific and medical device
specified in CISPR 11 or handheld transmitters used close to device. In these cases, special
mitigation measures may be required.
The industrial environment can be modified by adopting special mitigation measures.
After adopting these measures, if an electromagnetic environment equivalent to the
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. For each test specified in Tables 1~4, they shall comply
with one of the following general criteria:
a) Performance criteria A: During and after the test, the EUT shall continue to
operate in the intended manner. When the EUT is used in the intended manner,
its performance degradation or loss of function is not allowed to fall below the
performance level specified by the manufacturer. If the manufacturer does not
specify the performance level, it can be obtained from the product manual and
product documentation, or from the reasonable expectations of the user when the
device is used in the intended manner.
b) Performance criteria B: After the test, the EUT shall continue to operate in the
intended manner. When the EUT is used in the intended manner, its performance
degradation or loss of function is not allowed to fall below the performance level
specified by the manufacturer. The performance level may be replaced by an
allowable loss of performance. During the test, performance degradation is
allowed, but the actual working state or stored data is not allowed to change. If
the manufacturer does not specify a minimum performance level or an allowable
loss of performance, both can be obtained from the product manual and product
documentation, or from the reasonable expectations of the user when the device
is used in the intended manner.
c) Performance criteria C: During the test, temporary loss of function is permitted
provided that the function is self-recovering or can be restored by operating the
controls.
If the EUT becomes unsafe or dangerous as a result of performing the tests specified in
this document, the device shall be considered to have failed the tests.
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. Both the configuration and
the operating mode during the test shall be accurately recorded in the test report.
If the device is part of a system, or can be connected to auxiliary device, the device
shall be tested with the auxiliary device connected to it in the minimum representative
configuration required to operate the port. Simulated auxiliary device may be used.
