Electromagnetic compatibility - Generic standards -
Immunity for residential, commercial and light-industrial
environments
1 Scope
The electromagnetic compatibility (EMC) immunity requirements specified in this Part
of GB/T 17799 are applicable to electrical and electronic equipment used in residential,
commercial and light industrial environments, covering the immunity requirements in
the frequency range of 0 Hz~400 GHz. Frequency bands not specified in this Part do
not need to be measured.
If there are no relevant specific product or product type EMC immunity standards, the
general EMC immunity standards in this Part apply.
This Part applies to equipment directly connected to the low-voltage public mains
network or to a dedicated DC power supply powered by a low-voltage public mains
network. This Part also applies to battery-powered equipment or equipment powered
by non-public, non-industrial low-voltage distribution systems that are to be used in the
locations described below.
The environments included in this Part are indoor and outdoor environments in
residential, commercial and light industrial premises. The descriptions of some site
environments are listed below, including (but not limited to):
- Residential place, such as: residence, apartment, etc.;
- Retail outlets, such as stores, supermarkets, etc.;
- Commercial buildings, such as offices, banks, etc.;
- Public entertainment areas, such as: cinemas, public bars, dance halls, etc.;
- Outdoor places, such as gas stations, parking lots, playgrounds and sports centers,
etc.;
- Light industrial places, such as workshops, laboratories, maintenance centers, etc.
Any place that receives low-voltage power supply directly from the public mains
network belongs to residential, commercial and light industrial environments.
The purpose of this Part is to specify the immunity test requirements for continuous and
transient conducted and radiated disturbances, including electrostatic discharge, for
equipment within the applicable scope.
This Part specifies immunity requirements to ensure adequate immunity levels for
equipment operating in residential, commercial and light industrial environments.
However, these immunity levels do not include some extreme conditions that may occur
in any location with a very low probability. The tests recommended in this Part do not
include all disturbance phenomena, but only those related to the equipment covered by
this section are considered. These test requirements represent basic EMC immunity
requirements.
NOTE 1: For information on other harassment phenomena, see IEC 61000-4-1 [1].
This Part specifies test requirements for each port considered.
NOTE 2: Safety considerations are outside the scope of this Part.
NOTE 3: Under special circumstances, the disturbance level may exceed the test levels specified
in this Part. For example, use a handheld transmitter close to the device. In these cases, specialized
mitigation measures are required.

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

following criteria, record in the test report.
a) Performance criteria A
During and after the test, the equipment shall operate continuously in the intended
manner. No degradation in performance or loss of functionality below the
manufacturer's specified performance level shall be allowed when the equipment
operates as intended. Performance levels may be replaced by allowable
performance losses. If the manufacturer does not specify a minimum performance
level or allowable loss of performance, both can be derived from the product
instructions and product documentation; or from the reasonable expectations of
the user when the equipment is used in the intended manner.
b) Performance criteria B
After the test, the equipment shall continue to operate in the intended manner. No
reduction in performance levels or loss of functionality below the manufacturer's
specified performance levels shall be permitted when the equipment is used in the
manner intended. Performance levels can be replaced by allowable performance
losses. During the test, the performance level is allowed to be reduced, but the
actual working status or stored data is not allowed to change. If the manufacturer
does not specify a minimum performance level or allowable loss of performance,
both can be derived from the product instructions and product documentation; or
from the reasonable expectations of the user when the equipment is used in the
intended manner.
c) Performance criteria C
Temporary loss of function is permitted provided that such function is restored by
itself or by operation of the controls.
5 Test conditions
The equipment under test shall be tested in the expected most sensitive operating mode
(e.g., determined by limited pre-testing). This working condition shall be consistent
with normal usage. Test specimen configurations shall be varied to obtain maximum
sensitivity in typical applications and actual installations.
If the equipment is part of a system or can be connected to auxiliary equipment, the
equipment shall be tested with a minimum and representative number of auxiliary
equipment connected to the ports that must be used. A similar description can be found
in GB/T 9254.
If the manufacturer's technical specifications specifically require external protective
devices or measures, and this has been clearly stated in the user's manual, appropriate
external protective devices or measures must be used when applying the test
requirements of this Part.
The test layout and working conditions during the test shall be accurately recorded in
the test report. When it is not possible to test every function of the equipment, the most
critical working conditions shall be selected for testing.
If a device has many similar ports or certain ports have many similar connections, then
a sufficient number of ports shall be selected to simulate actual working conditions to
ensure that all different types of terminals are involved.
Tests shall be conducted at rated power supply voltage within the temperature, humidity
and air pressure ranges specified for the product, unless otherwise specified in the
underlying standard.
6 Product documentation
If the manufacturer requires the use of its own technical specifications to assess the
EMC performance compliance or degradation of the product during or after testing in
accordance with this Part, this shall be stated in the user documentation. The
manufacturer shall be able to provide such technical specifications when required.
7 Applicability
The application of immunity testing depends on the specific equipment and its
configuration, ports, technology, process and operating status.
The relevant ports of the equipment shall be tested according to the requirements of
Table 1 ~ Table 4. Testing shall only be performed when the port in question is present.
Which tests are inappropriate and unnecessary can be determined based on the electrical
characteristics and intended use of the specific equipment. In this case, the reasons for
not testing shall be recorded in the test report.
8 Immunity test requirements
The equipment immunity test requirements involved in this Part are given based on the
port.
Testing shall be performed in a fully defined and reproducible manner.
The tests shall be carried out one by one in a single test sequence. The order of tests is
arbitrary.
