仿真饰品中镍释放量测定能力验证的组织与实施

Organization and Implementation of Proficiency Testing for Determination of Nickel Release from Simulation Jewelry

为了了解我国仿真饰品中镍释放量检测能力的整体水平,中国国家认证认可监督管理委员会(CNCA)组织了"CNCA–12–B07仿真饰品中镍释放量的测定"能力验证项目,该项目共有来自12个省市、特别行政区的38家实验室参加。镍释放量主要采用GB/T 19719–2005与EN 1811:2011进行检测,对检测结果采用稳健(Robust)统计方法分析。结果显示,第1次测试结果合格率为89.5%。

In order to learn about the total level of determination of nickel release in the simulation jewelry, the proficiency testing project about determination of nickel release in the simulation jewelry （CNCA-12-B07） was organized by the Certification and Accreditation Administration of China Determination （CNCA） in 2012. 38 laboratories from 12 provinces and special administrative region took part in the testing. GB/T 19719-2005 and EN 1811：2011 were adopted for detection and the results were analyzed by the robust statistical method. The acceptability of the first test results was 89.5%.
