Testing Method Standards:
GB/T 9791-2003 Test Method for Chromate Conversion Coatings on Zinc, Cadmium, Aluminum Zinc Alloys, and Zinc Aluminum Alloys
This standard specifies the testing methods for the following items:
- the presence of colorless chromate conversion coatings The presence and content of hexavalent chromium in colorless and colored chromate conversion coatings of zinc, cadmium, aluminum (mass fraction 55% Al) - zinc alloy and zinc aluminum (mass fraction 5% Al) alloy
- Total chromium content per unit area of zinc and cadmium
- Mass per unit area of colorless and colored films
- Satisfactory adhesion of chromate conversion film
- Quality of chromate film. These methods are applicable to:
- colorless and colored chromate conversion films produced by chemical or electrochemical methods, containing different proportions of trivalent chromium and hexavalent chromium
- Only applicable to chromate conversion coatings without any additional covering layer (such as oil film, water-based or solvent based polymer film, or wax film) What is the testing fee
