1 Scope
This document describes the testing method for the qualitative analysis of hexavalent chrome in corrosion
protection layers.
2 Principle
The coated part to be examined (test sheet metal, construction unit) is extracted and the Cr(VI) content in the
extracted solution is determined according to the colour reaction with 1,5-diphenylcarbazide. Cr(VI) oxidises
1,5-Diphenylcarbazide to diphenylcarbazone, which forms a red-violet coloured complex with the developed
Cr(III). The evaluation is made by visual inspection of the coloured solution.
3 Apparatus
Normal laboratory apparatus and the following:
