\nTest Methods of Hexavalent Chromium in Automobiles Materials<\/p>\n

<\/p>\n

1 SCOPE<\/p>\n

This standard specifies the methods for determining the hexavalent chromium (Cr(VI)) content in automobile parts and materials, where,
\n“X-ray fluorescence spectrometry” is applicable to screening and rapid determination of Cr(VI) content in automobile materials by using X-ray fluorescence spectrometry.
\n“Qualitative test for the presence of hexavalent chromium in anti-corrosive metal coatings” is applicable to determining the presence of Cr(VI) in anti-corrosive coatings of automobiles by using spot-test procedure and boiling water extraction procedure. “Determination of hexavalent chromium content in anti-corrosive metal coatings” is applicable to determining the Cr(VI) content in anti-corrosive coatings by using boiling water extraction procedure and colorimetric method. The above two test methods are applicable to the coatings without any additional covering layer, e.g. oil film, water-based or solvent-based polymer film or waxy film.
\n“Determination of hexavalent chromium content in polymer materials and electronic materials” is applicable to determining the Cr(VI) content in polymers and electronics by using alkaline extraction method and colorimetric method, but not applicable to PE or EVAC material. The Cr(VI) content in other automobile materials, e.g. glass, ceramics, fabrics, and paint coatings, can be determined by reference to this method.
\n“Determination of hexavalent chromium content in leather materials” is applicable to determining the Cr(VI) content in leather materials by using phosphate solution extraction method and colorimetric method.<\/p>\n
