1 Scope
This document specifies the general immunity requirements for electromagnetic compatibility (EMC) of electrical and electronic equipment and systems used in industrial machinery. This document applies to electrical and electronic equipment and systems for industrial machinery, or parts thereof, for which no dedicated product or product-family immunity standards exist. The nominal power supply voltage does not exceed 1,000 V AC or 1,500 V DC, and the nominal frequency does not exceed 200 Hz.
Note 1: If there are relevant dedicated product or product-family EMC immunity standards, those product standards or product-family standards take precedence over this document in all aspects.
Note 2: The general immunity requirements specified in this document for electrical and electronic equipment and systems of industrial machinery are intended to ensure they have a suitable level of immunity. However, these immunity levels do not address extreme situations which may occur in any location but are highly improbable. The immunity tests in this document do not cover all electromagnetic disturbance phenomena, only those relevant to this document.
Note 3: This document specifies test requirements for each port considered. This document does not include considerations for safety aspects.
Note 4: In some special cases, disturbance levels exceeding the test levels specified in this document may occur. For example, electrical systems of industrial machinery installed close to industrial, scientific, and medical (ISM) radio-frequency equipment as defined in GB 4824-2019, or the use of handheld transmitters near electrical systems. Where necessary, specific mitigation measures should be considered.

3 Terms and Definitions
For the purposes of this document, the terms and definitions given in GB/T 4365-2024, GB 4824-2025, and the following apply.
3.1
port
specified interface between a given equipment and the external environment.
Note: Examples of ports are shown in Figure 1.
Figure 1 Examples of ports
3.2
enclosure port
physical boundary of an equipment through which electromagnetic fields can radiate or impinge.
3.3
signal port
port on equipment to which cables or wires for data signal transmission are connected.
Example: data buses, communication networks, and control networks.
3.4
power port
port on equipment to which cables or wires supplying power to the equipment or its auxiliary equipment are connected.
4 Performance Criteria
4.1 General
If the electrical equipment or system becomes unsafe or hazardous as a result of testing according to the provisions of this document, the equipment shall be deemed to have failed the immunity test.
During or after the immunity test for electrical equipment of industrial machinery, its functional description and the definition of specific performance criteria shall be provided by the manufacturer and recorded in the test report according to the following general criteria.
4.2 Performance Criterion A
During and after the test, the equipment under test (EUT) shall continue to operate as intended. When the EUT is used as intended, its performance degradation or loss of function shall not fall below the performance level specified by the manufacturer. The performance level may be replaced by allowable performance degradation or loss of function.
If the manufacturer does not specify a minimum performance level or allowable loss of function, these may be derived from the product instruction manual or product documentation; alternatively, they may be derived from the reasonable expectation of the user when the EUT is used as intended.
4.3 Performance Criterion B
After the test, the EUT shall continue to operate as intended. When the EUT is used as intended, its performance degradation or loss of function shall not fall below the performance level specified by the manufacturer. The performance level may be replaced by allowable performance degradation or loss of function.
During the test, performance degradation is allowed, but the actual operating status or stored data shall not change. If the manufacturer does not specify a minimum performance level or allowable loss of function, these may be derived from the product instruction manual or product documentation; alternatively, they may be derived from the reasonable expectation of the user when the EUT is used as intended.
4.4 Performance Criterion C
Temporary loss of function is allowed, provided the function recovers automatically or can be restored by operation of a control.
