Comparative analysis of calibration procedures in current and proposed editions of the IEC 61000-4-2 Standard

The IEC 61000-4-2 Standard has been used in the last decades as the main Test Standard for commercial ESD testing extensively. A new edition of this Standard is currently under work and some of its potential changes will affect the ESD generator calibration procedure significantly. In an effort to improve reproducibility between the different calibration laboratories a new waveform parameter is added. In this work, calibration measurements according to the current edition 2 and the proposed edition 3 of IEC 61000-4-2 are carried out for a commercially available ESD generator. The calibration results are presented and the emerged issues are discussed.
