For the test method of conducted disturbance, see GB/T 6113.201-2017.
For the measurement method of radiated disturbance, see GB/T 6113.203.
Note: The test methods for harmonics, voltage fluctuations and flicker are given in Clause 7.
network is used for the power port, see Figure 1). Regardless of grounding or not, table-top service robots shall be placed as follows:
- The bottom or back of the service robot shall be placed at a steerable distance of 40 cm from the reference ground plane. The ground plane is
usually a wall or floor of shielded room. It may also be a grounded metal plate of at least 2 m??2 m;
Note 1: The actual arrangement can be achieved as follows:
The service robot is placed on a test bench of insulating material at least 80 cm high, which is 40 cm away from any wall of the shielded room. Or the service robot is placed on a 40 cm high test bench of insulating material, so that the bottom of the service robot is 40 cm above the ground plane.
- The distance between all other conductive planes of the service robot and the reference ground plane shall be greater than 40 cm;
- The cable connection of the service robot is shown in Figure 1;
- As shown in Figure 1, those artificial mains networks are placed on the floor in such a way that one side of the artificial network enclosure is 40 cm from the vertical reference ground plane and other metal components. The V-
type artificial mains network and the Y-type impedance stabilization network are shown in Figure 1 and Figure 2.
Note 2: The configuration shown in Figure 3 may create some uncertainty, because the metal interference source for some service robots is not at the center of the non-metallic enclosure (see GB/Z 6113.401).
aspect ratio of no more than 3:1, this requirement can be achieved. The resonance of the AMN grounding can be determined by field test of the voltage division coefficient (see GB/T 6113.201-2017, Appendix E).
The arrangement of the service robot is as shown in Figure 1~Figure 4. The distance between the boundary of the service robot and the nearest surface of the AMN is 80 cm. The method of placing the table-top service robot in Figures 1 through 4 is to mount the AMN on a ground plane ?€??€? the front panel is flush with the ground plane.
The power lines to the AMN and the connection cables from the AMN to the measurement receiver shall be placed so that their positions do not affect the measurement results. For service robots which do not have a fixed connection cable, according to the provisions in the relevant service robot documentation, USE a 1 m long wire to connect to the AMN. The 1 m long wire is chosen
because of its low standard compliance uncertainty.
Unless the service robot has special requirements for ground impedance, the following provisions shall apply. If the service robot is to be connected to the reference ground, it shall use a wire which is parallel to the power line and has the same length and is no more than 10 cm away, unless the power line itself contains a ground wire. If the service robot has a fixed power line, the wire shall be 1 m long. If it exceeds 1 m, a part of the wire shall be folded back and forth into an S-shape, to form a wiring harness having a length of 30 cm~40 cm as much as possible; and placed in a noninductive S-shaped curve shape, so that the total length of the power line does not exceed 1 m. However, when the folded and bundled power line may affect the measurement results, the length of the power line shall be shortened to 1 m.

6.2.2.1 Test arrangement of table-top service robot
Robots used as table-top service robots shall be placed on non-metallic tables. The size of the tabletop is typically 1.5 m??1.0 m. However, the actual size depends on the horizontal size of the service robot.

If not under normal use, the spacing distance between adjacent units during the test arrangement shall be 0.1 m. The cable between the units shall hang down from the back edge of the test table. If the distance between the drooping cable and the horizontal ground plate is less than 0.4 m, the extra-long part of the cable shall be folded back and forth at its center and bundled in an 8-shape into a wiring harness of not 7 Harmonics, voltage fluctuations and flicker
