Description / Abstract: Specifies the requirements and the corresponding test methods for the pigments. They are classified in a table which gives the Colour Index Number and the approximate composition of the pigments. The pigments are divided into the standard type and the stabilized type. total lead content, a gravimetric and a titrimetric method are specified. The gravimetric method shall be used as the referee method. The extraction method for the determination of soluble-lead content described has been derived from ISO 6713:1984. Cancels and replaces ISO 3711:1976, of which it constitutes a technical revision.
