REAP
Rapid Electrochemical Assessment of Paint (REAP) allows determining the Time To Failure (TTF) within 24 hours by combining different techniques. During this protocol a series of measurements with multiple samples is performed and the long-term stability is extrapolated. Electrochemical Impedance Spectroscopy (EIS) and cathodic disbonding are the central techniques for the Rapid Electrochemical Assessment of Paint (REAP), which allows an estimation of the TTF.
See Chapter Rapid Electrochemical Assessment of Paint for an overview of the steps in REAP.

EIS Analyzer
An EIS Analyzer is a device that can measure how a particular substance or electrode surface responds to a a potential that is constantly increased and decreased within certain predefined limits (a potential wave).
Electrochemical Impedance Spectroscopy (EIS)
Electrochemical Impedance Spectroscopy (EIS) is an electrochemical technique to measure the impedance of a system in dependence of the AC potentials frequency.
