Abstract

Considerable variations in specific migration measurements are often observed when comparing results from different laboratories on identical plastic - additive - liquid systems. In order to determine the influence of the various parameters on reproducibility and repeatability in specific migration tests, and to develop an appropriate methodology, a collaborative study was undertaken with the participation of nine laboratories from the member countries of the EC. Irganox 1010 and dihydroxylphenyl, as model additives, were incorporated in extended high density polyethylene. A water - ethanol mixture, olive oil and a synthetic fat were selected as test liquid for contact with the plastics under well defined storage conditions. The study was carried out in four phases: - testing of a conventional HPLC method - testing and verification of a 14-C tracer technique - study of repeatability and reproducibility values in two-sided contact at constant temperature - investigation of the effect of storage conditions on repeatability and reproducibility criteria in one- and two-sided contact at two different temperatures. The collaborative exercise resulted in acceptable repeatability values for specific migration tests if storage conditions were accurately controlled.
