ESD-generatorer IEC61000-4-2

IEC 61000-4-2 is the international standard for electrostatic discharge (ESD) immunity testing within EMC. It ensures that electronic devices can withstand static electricity from users and the environment. Using IEC 61000-4-2 compliant test equipment allows accurate, repeatable ESD testing required for product certification and reliability. We offer complete solutions including ESD simulators (ESD guns), calibration, and accessories for development, pre-compliance, and full certification testing.

Purpose

This test is for electrical and electronic equipment subjected to electrostatic discharge (ESD) from operators/personnel directly touching equipment or being adjacent to the equipment

Contact Discharge Test Levels and Waveform Parameters

Test levels - all lower test levels must also be satisfied, i.e., if the test specification is 6 kV contact, then 2 and 4 kV must also be applied.

Applying the ESD test

• Points of application - all points that are accessible to the user in normal operation; not necessarily pins of open connectors nor points accessible only during maintenance or servicing.

• Application method - contact discharge is preferred; air discharge is used where contact cannot be applied; both direct discharges to the EUT and indirect discharges to the coupling plane(s) are required.

• Non-earthed apparatus - should be deliberately discharged between each pulse, e.g. via connection of bleed resistor or by air ionization.

• Number of discharges - normally ten in each polarity to each point of application – EN 55024 requires a total of 200, 50 at each point.

• Mode of application - test generator must be perpendicular to the surface of the EUT; for air discharge, the tip must approach the EUT as fast as possible without causing mechanical damage; for contact, the tip must touch the EUT before the discharge is cancelled.
