已生产两种聚合物（聚乙烯）参比物质，以支持关于塑料包装和包装材料的EC指令94/ 62/EC。本文描述了材料的制备，为表征其均匀性和稳定性而进行的分析工作，以及一系列元素的材料认证。还总结了结果的技术和统计评价。
Two polymer (polyethylene) reference materials have been produced in support of EC Directive 94/ 62/EC on plastic packaging and packaging material The paper describes the preparation of the materials, the analytical work performed to characterize their homogeneity and stability, and the certification of the materials for a range of elements. The technical and statistical evaluation of the results are also summarized.
