Industrial trucks—Electromagnetic compatibility
1 Scope
This standard specifies the requirements and the limit values for electromagnetic emission and immunity to external electromagnetic fields, and the test procedure and acceptance criteria for industrial trucks, regardless of the power source (called only trucks) as defined in GB/T 6104.1-2018, and their electrical/electronic systems (called only systems).
This standard is applicable to trucks and their systems when used in residential, commercial, light industry and industrial environments (specified in GB 17799.3-2012 and IEC 61000-6-2:2016).
This standard is not applicable to:
—non-stacking low-lift straddle carriers;
—stacking high-lift straddle carriers;
—any pedestrian propelled trucks, excepted those which are equipped with load handling devices which have electrical powered lifting devices;
—trucks intended for use on ordinary highways with maximum speed exceeding 30 km/h;
—positioning system of driverless industrial trucks;
—interaction between systems on the trucks;
—interference to on-board radio equipment;
—equipment connected to AC-mains which is only used when the truck is not being operated (e.g. on-board charger).

3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 10827.1 and the following apply.
3.1
test sample

Note 1: Motors and generators are examples of electrical machines.
Note 2: The system configuration is set up with maximum cable and harness lengths.
3.2
electrical/electronic system
electrical/electronic component(s) or a set of components intended to be part of a machine together with any associated electrical connections and wiring, that performs one or more specialized functions and operates on its own
3.3
narrowband emission
emission that has a bandwidth less than that of a measuring apparatus radio receiver
Note 1: The bandwidth set at 9 kHz from 0.15 MHz–30 MHz and 120 kHz above 30 MHz.
