Industrial trucks - Electromagnetic compatibility
1 Scope
This Standard specifies the requirements and limits, test procedures and judgment
criteria for electromagnetic emission and immunity to external electromagnetic fields
of industrial vehicles that use any power source (hereinafter referred to as vehicles) and
their electrical/electronic systems (hereinafter referred to as systems) defined in GB/T
6104.1-2018.
This Standard applies to vehicles and their systems used in residential, commercial,
light industrial and industrial environments (see GB 17799.3-2012 and IEC 61000-6-
2:2016).
This Standard does not apply to:
- Low-lift straddle carriers for non-stacking;
- High-lift straddle carriers for stacking;
- Pedestrian vehicles, other than vehicles equipped with load handling devices with
electric lift;
- Vehicles with a maximum speed of more than 30km/h on ordinary roads;
- Positioning systems for unmanned industrial vehicles;
- Mutual interference between vehicle systems;
- Interference problems of in-vehicle wireless communication equipment;
- Devices (such as a car charger) connected to AC power and only used when the
vehicle is not moving.

3 Terms and definitions
For the purposes of this document, the terms and definitions defined in GB/T 10827.1
as well as the followings apply.
3.1 test sample
vehicles and/or their electrical/electronic systems, electrical equipment, system
configurations used for type test
NOTE 1: Electric motors and generators are examples of electrical equipment.
NOTE 2: System configuration with maximum length of cable and wiring.
3.2 electrical/electronic system
a combination of electrical/electronic components or parts connected by ancillary
electrical connections and cables, capable of working independently and performing
one or more specific functions as part of a machine
3.3 narrowband emission
significantly from the manufacturer's instructions, the vehicle/system needs to be tested.
NOTE: The entire system refers to the internal combustion engine or the electrical/electronic
module.
All test results, test procedures and working modes during the test shall be accurately
recorded in the test report.
5.2 Electromagnetic field emission test
5.2.1 General requirements
The emission of all functions/units of the vehicle/system shall be tested in accordance
with the methods of 5.2.3, 5.2.4, 5.2.5, 5.2.6. System tests can be performed separately
or in any combination.
The emission value shall meet the limit requirements specified in 4.1.
5.2.2 Test and measurement instruments
Test and measurement instruments shall comply with CISPR 16-1-4:2019 and CISPR
16-1-1:2019 (except for antenna location).
5.2.3 Test steps
Antenna shall be 3m high. Place it 10m away from the side of the vehicle/system.
According to Figure 2, the antenna shall be at right angles to the specimen except for
the load handling device and located on its centerline.
The test shall be performed on both sides of the vehicle/system. The antenna is in both
vertical and horizontal polarization states.
When the above steps are completed, determine from the results the five radiated peak
frequencies associated with the reference limit curve. Then by changing the height of
the antenna (from 2m to 4m), repeat the test according to the above frequency, so as to
determine that the measured value does not exceed the reference limit curve.
When electrical components emit narrowband emissions, the narrowband emissions
shall be measured using an EMI receiver with averaging or quasi-peak filtering.
NOTE 1: For other relevant information, see GB 14023-2011.
When a high-voltage ignition internal combustion engine system emits broadband
emissions, the broadband emissions shall be measured using an EMI receiver with
quasi-peak filtering.
NOTE 2: For other relevant information, see GB 14023-2011.
shall be set to the maximum operating speed.
For internal combustion vehicles, the spark ignition engine shall run at 1500r/min.
Diesel engines shall run at a low idle speed of 1.5 times.
5.2.5 Load handling drive system test driven by electric motor
When the load handling drive system can be controlled by pulse width modulation, the
motor speed shall be controlled to 60% to 80% of the maximum speed. When there is
no speed control, the motor speed shall be set to the maximum operating speed. If the
specifications of the vehicle hydraulic system prohibit continuous operation, the
hydraulic system of the test vehicle shall be modified. Enable the test procedure to
proceed.
When the motor of the low-lift vehicle is allowed to open time to prohibit its continuous
operation, the test shall be carried out using a spectrum analyzer (the filter shall be
adjusted to the peak mode). In this case the frequency range can be divided into 10 sub-
