On December 7, 2019, the European Union Reference Laboratory for Food Contact Materials (EURL-FCM) reported on the outcomes of a proficiency test organized “to assess the analytical performance of National Reference Laboratories (NRL) and Official Control Laboratories (OCL) in the determination of mass fractions of polyethylene terephthalate (PET) and polybutylene terephthalate (PBT) cyclic dimers and trimers in official food simulant.” Measurement data were obtained from “a total of 36 participants from 26 countries” and results were found to be “satisfactory” for “most of the participating laboratories.” The EURL-FCM concludes that the performed proficiency test, “organized for the first time at EU level, shows that most of the NRLs and OCLs are able to monitor the investigated measurands.”
