Simulates electrostatic discharge events directly to the product, or to a nearby conductive surface.
Test Method
The ESD test requires that discharges be made to all exposed surfaces of the EUT, including connector back shells. Contact discharge is to the conducting surfaces of the product and air gap discharges are to non-conducting surfaces. The test also requires that contact discharges be made to a horizontal reference plane and vertical reference plane at locations 10cm from the front, rear and sides of the EUT. The ESD Simulators/Generators/Guns can be used for ESD Testing.
Typical rise time of the ESD pulse waveform is approximately 0.7 - 1nS with a hold time of 30 - 60 nS. (See image)
The test simulates ESD events that occur when the user touches the equipment under test or nearby metallic objects (e.g. filing cabinets). The test levels for both the heavy industrial and light industrial/commercial/residential standards are ±2kV and ±4kV for the contact discharge method and ±2kV, ±4kV, and ±8kV for the air gap discharge method.
