We are doing science for policy
The Joint Research Centre (JRC) is the European Commission's science and knowledge service which employs scientists to carry out research in order to provide independent scientific advice and support to EU policy.
The migration of substances from plastic materials to contacting media obeys in most cases the law of diffusion because the diffusion process is the rate determining step. Due to advanced understanding of the mass transfer processes and translation into science-based computational tools, migration modelling has often become the method of choice for compliance testing by industry. Official controls should be able to have state of the art knowledge on theory and practice on the latest softwares in order to perform their duties on examining certificates of compliance.
A first course was organised in 2006. On 15th and 16th of April 2010 an advanced training was organised . As a follow up, JRC prepared a set of 10 modelling exercises from simple to complex. The set of exercises covered monolayers, multi-layers, kitchen articles, gaskets and adhesives. This exercise was aimed as a proficiency testing which circulated to Member States official controls with a one month time for completion. A two-month free use was kindly granted for the 3 software's to all NRLs to practice the exercises. All results were compiled and evaluated by the EURL and the exercises were corrected and discussed in presence of the expert trainers on 30th of June 2010. This completed the activities foreseen in 2010 on migration modelling in support to plastics Directive 2002/72/EC and amendments. The customer satisfactions surveys have been very positive, and the success was such that official controls agreed to have periodic test (exercise set and correction) in 2011 to maintain the acquired capacity.
