ISO 10775:2013 specifies a method for the determination of traces of cadmium in all types of paper, board and pulp, including products containing recycled fibre, that can be wet-combusted in nitric acid as specified in ISO 10775:2013.
The lower limit of the determination depends on the equipment used and is normally about 10 μg/kg. Cadmium present in pigments and fillers that do not dissolve in nitric acid under the conditions of this test may not be determined quantitatively.
