BS 3900-B8 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-B8 describes a flame atomic emission spectrometric (AES) method for the determination of the barium content of the test solutions prepared according to ISO 6713 or other suitable International Standards. The method is applicable to paints having “soluble” barium contents in the range of about 0,05 to 5 %(m/m).
BS 3900-B8 on liquid paints and dried paint films is useful for:
Barium is utilized as a part of white color for paints. In oil paint, barium is practically transparent, and is utilized as a filler or to alter the consistency.
BS 3900-B8 describes a chemical method for determining the soluble barium in liquid paints and dried paint films. BS 3900-B8 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 barium present that aids in determining the colour characteristics of the liquid paints and dried paint films.
