This European Standard specifies methods to measure the temperature reached by plastics materials and articlesin contact with foodstuffs during microwave heating and conventional oven heating in order to select theappropriate temperature for migration testing.It is applicable to all plastics materials and articles for which the food(s) with which they can come into contactunder worst foreseeable conditions of use is/are known. This includes pre-packaged foods such as ready mealswhich will be heated in the packaging, and for foods which need some pre-preparation but which include thecooking container in the pack, e.g. cake mixes. The method is also suitable for plastics materials and articles to beused for preparing foods in the home or for use in commercial food preparation where the article is supplied as astand-alone item, i.e. not containing or not including food at the point of sale.NOTEAlthough the method has been developed for plastics materials and articles, it is also applicable to other packagingmaterials including paper and board, rubber and elastomers, ceramics, glass etc. Temperature measurements usingconventional oven heating are suitable for metal materials but these items should generally not be heated in microwave ovensdue to possible problems with arcing.
