This document is one in a series of standards for the determination of metals in aqueous extracts of paper and board intended for contact with food. This document specifies the test method for the determination of aluminium in aqueous extracts. It is applicable to paper and board with extractable metal contents exceeding 0,2 mg aluminium per l extract. Aluminium extract levels below those given can be measured using this document if sensitive equipment is available and if all other laboratory conditions fulfil the requirements for trace element analysis.
