| Abstract: | In order to control the quality of trace element determinations in polymer, the Standards, Measurements and Testing Programme
(formerly BCR) of the European Commission has started a project of which the final aim is to certify polymer reference materials
for their contents of a range of trace elements. The first part of this project consisted in an interlaboratory study which
aimed at testing the feasibility of preparation of candidate polymer reference materials and to detect and remove most of
the pitfalls observed in trace element determinations. This paper presents the results of this interlaboratory study carried
out prior to the certification campaign.
