This standard specifies methods for the determination of ash content in solvent dyestuff and dyestuff intermediates. Ash is determined by burning the sample at high temperatures and the remaining inorganic matter mass. The standard provides the dyestuff industry with accurate ash determination methods to ensure the mass and purity of dyestuff products and help control the impurity content in the production process.
