Description

The calibration foils data include the results of the impedance spectrum measurements of the 110-, 135-, 185-, and 240-μm foils recorded inside the Faraday cage at an amplitude of 250 mV, and the impedance spectrum and impedance measurements at a single frequency of 0,1 Hz of the 240-μm film recorded outside and inside the Faraday cage at each signal amplitude from 10 to 250 mV in the presence of AC interference (0, 25, 50, 100, 250, 800 mV). The coating data contains the results of Log Z measurements on the four coated systems subjected to AC interference (50±7 mV) in the field at the signal amplitudes of 250 mV. The dummy cell data include the results of the impedance spectrum and impedance measurements at a single frequency of 0.1 Hz of the dummy cell recorded at the signal amplitudes of 10 and 250 mV in the presence of AC interference (250 mV).
