Determination of certain substances in electrotechnical products - Determination of the presence of hexavalent chromium (Cr(VI)) in colorless and colored corrosion-protected coatings on metals by the colorimetric method Ingestion-build-143074 pin type (including pin-post type)1 Scope This part of IEC 62321 describes a boiling water extraction procedure intended to provide a qualitative determination of the presence of hexavalent chromium (Cr(VI)) in colourless and coloured corrosion protection coatings on metallic samples. Due to its highly reactive nature, the concentration of Cr(VI) in a corrosion protection coating can change drastically with time and storage conditions. Since storage conditions prior to sample
