3 ISO 10605 Bench Setup

The TI ESD test bench set up complies with the ISO 10605 standards as shown in Figure 3-1. The Device under Test (DUT) is placed on a horizontal coupling plane (HCP). Two 470-kΩ resistors in series connect the HCP to the ground reference plane (GRP), and all devices are placed on a non-conductive table. Unlike IEC 61000-4-2, ISO 10605 is supposed to simulate the discharge of a device into a vehicle, so the generator (referred to as ESD simulator in Figure 3-1) is grounded to the table (upper HCP) instead of the earth. That is because the table is supposed to act as an independent body isolated from the earth. The illustration in Figure 3-1 gives a basic overview of the rest of the setup. Note the grounding of the simulator to the table (HCP) instead of the floor.
