Scope

This International Standard specifies the procedure for evaluation of the experimental set-up of electrochemical measurements on high-impedance coated samples using methods that are based on the current interrupter (CI) technique, relaxation voltammetry (RV) or DC transient (DCT) measurements.It provides specific definitions and guidance on optimizing the collection of CI, RV and DCT data from highimpedance systems. High impedance in the context of intact coatings refers to systems with an impedance greater than 109 Ω/cm2. This does not preclude measurements on systems with lower impedance. This International Standard deals in particular with: — instrumenta
