Abstract
Two polymer (polyethylene) reference materials have been produced in support of EC Directive 94/ 62/EC on plastic packaging and packaging material The paper describes the preparation of the materials, the analytical work performed to characterize their homogeneity and stability, and the certification of the materials for a range of elements. The technical and statistical evaluation of the results are also summarized.
