The development of European standard (CEN) methods in support of European Directives for plastics materials and articles intended to come into contact with foodstuff.
CEC Directives have been implemented for plastics materials and articles intended to come into contact with foodstuffs. These introduce limits upon the overall migration from plastics into food and food simulants. In addition, specific migration limits or composition limits for free monomer in the final article, have been set for some monomers. Agreed test methods are required to allow these Directives to be respected. CEN, the European Committee for Standardization, has created a working group to develop suitable test methods. This is 'Working Group 5, Chemical Methods of Test', of CEN Technical Committee TC 194, Utensils in contact with food. This group has drafted a ten part standard for determining overall migration into aqueous and fatty food simulants by total immersion, by standard cell, by standard pouch and by filling. This draft standard has been approved by CEN TC 194 for circulation for public comment as a provisional standard, i.e. as an ENV. Further parts of this standard are in preparation for determining overall migration at high temperatures, etc. Simultaneously, Working Group 5 is cooperating with the BCR (Community Bureau of Reference) to produce reference materials with certified values of overall migration. CEN TC 194 Working Group 5 is also drafting methods for monomers subject to limitation in Directive 90/128/EEC. Good progress is being made on the monomers of highest priority but it is recognized that developing methods for all the monomers subject to limitation would take many years. Therefore, collaboration with the BCR, the Council of Europe and others is taking place to accelerate method development.
