Abstract: An intercomparison to establish the performance of routine laboratories in the determination of polybrominated flame retardants in polymers was organised. Commercial poly(ethyleneterepfhthalate) (PET) was fortified with technical Penta-, Octa-, and Deca-BDE mixtures and with Deca-BB technical mixture at 0.4 to 0.8 g/kg. Homogeneity and stability of the total Br content in the material was confirmed. Thirty-seven laboratories from Europe, Asia and the Americas submitted results. Repeatibility standard deviations for individual congeners ranged from 7 to 17 %. Between-laboratory standard deviations ranged from 22 to 61 %. No significant influence of a common standard, application of a standard method or method parameters could be identified. The quality and uncertainty of the results of this study are significantly worse than those reported in the environmental field and indicate a clear need for a learning process among the laboratories involved.
