Determination of galvanic corrosion rate for assembled forms of carbon fibre reinforced plastics (CFRPs) and protection-coated metal. Electrochemical tests in neutral sodium chloride solution. | Status: Current

1 Scope 1.1 This document specifies the electrochemical test for determining galvanic corrosion rate of CFRPs and metal assemblies with protection-coating, subjected to the corrosive environment of electrolyte diffusion through the coating. It specifies the apparatus, the test solutions, and the procedure to be used in conducting the electrochemical tests for

1. a) the assessment of the Fick's diffusion parameter for protective coating on metallic materials, and
2. b) the estimation of the galvanic corrosion rates with the conversion of ISO 21746 coating-free sample data.
