This standard specifies the procedure for evaluation of the experimental setup of electrochemical measurements on high impedance coated samples using methods that are based on current interrupter technique (CI), relaxation voltammetry (RV) or DC transient measurements (DCT). This standard provides specific definitions, guidance on optimizing the collection of CI, RV and DCT data from high-impedance systems. High impedance in the context of intact coatings refers to systems with an impedance greater than 109 O/cm2. This does not preclude measurements on systems with lower impedance. This standard deals in particular with: - instrumental set-up: requirements and shortcomings; - data validation: checking the measurement range and the accuracy of the data; - performing CI, RV, DCT measurements: specimen considerations and instrumental parameters; - the experimental results: different methods of presenting CI, RV and DCT data. Following the recommendations should ensure the acquisition of CI, RV and DCT data that can be used to study the performance of the specimen. It does not give guidelines for the interpretation of the data.
