What is BS 3900-B7 - Liquid paints and dried paint films about?
BS 3900-B7 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 3900-7 describes two methods for the determination of the antimony content of the test solutions prepared according to ISO 6713 or other suitable International Standards. The methods are applicable to paints having “soluble” antimony contents in the range of about 0,05 to 5 % (m/m). The flame atomic absorption spectrometric (AAS) method should be used as the referee method in cases of dispute. Other methods can be used by agreement between the interested parties. If a spectrophotometric method is agreed, the Rhodamine B spectrophotometric method should be used.
Who is BS 3900-B7 Liquid paints and dried paint films for?
BS 3900-B7 on liquid paints and dried paint films is useful for:
- Paint manufacturers
- Testing laboratories
- Quality control personnel
Why should you use BS 3900-B7 - Liquid paints and dried paint films?
Paint production uses numerous chemicals to decorate, protect and prolong the life of natural and synthetic materials.
BS 3900-B7 describes a chemical method for determining the soluble antimony in liquid paints and dried paint films. BS 3900-B7 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 antimony present that aids in determining the characteristics of the liquid paints and dried paint films.
