Determination of certain substances in electrotechnical products - Hexavalent chromium. Determination of hexavalent chromium (Cr(VI)) in polymers and electronics by the colorimetric method Ingestion-build-58320 BS IEC 62899‑204 defines theWhat is BS EN 62321 7 2 Determination of Hexavalent chromium in electrotechnical products about? BS EN 62321 7 2 is the second subpart of the seventh part of the multi series standard that focuses on the determination of certain substances in electrotechnical products. BS EN 62321 7 2 describes procedures to measure hexavalent chromium, Cr(VI), quantitatively in samples of polymers and electronics. This method employs organic solvent to dissolve or
