BS 3900- B10 discusses test methods for paints. The aim of the BS 3900-B series is to provide the best industrial practice to determine the metal content in paint by the spectrometric method.
BS 3900- B10 describes a diphenylcarbazide spectrophotometric method for the determination of the “soluble” hexavalent chromium content of the hydrochloric acid extract of the pigment portion of the liquid paint or of the paint in powder form.
BS 3900- B10 on liquid paints and dried paint films is useful for:
Paint production uses numerous chemicals to decorate, protect and prolong the life of natural and synthetic materials. Chromium compounds are added to paints and primers to provide corrosion protection and reflective properties.
BS 3900- B10 describes a laboratory method for determining hexavalent chromium content in liquid paints and dried paint films. BS 3900- B10 covers the principle of the test method, reagents and materials, procedure, expression of result, and test report. This can help to determine the quantity of hexavalent chromium content present that aids in determining the characteristics of the liquid paints and dried paint films.
