Abstract
What is BS 3900-B4 - L iquid paints and dried paint films about?
BS 3900-B4 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 3900-4 describes a flame atomic absorption spectrometric method for the determination of total lead in paints and related products. The method is applicable to products having total lead contents in the range of about 0,01 to 2 % ( m / m ). Two methods are given for the treatment of the test portion; the dry ashing method should be used as the referee method in cases of dispute. For the determination of lead in the test solution, the dithizone spectrophotometric method specified in ISO 3856/1 may be used as an alternative method.
