不同实验室结合苯乙烯含量测定结果比对

Determination result comparison of bound styrene contents of different laboratories

实验室间的数据比对是判断和监控实验室能力的有效手段,文中阐述了国家合成橡胶质量监督检验中心对苯乙烯—丁二烯橡胶中的结合苯乙烯含量的数据比对分析。用稳健统计技术处理及Z比分值计算,结果表明,大部分实验室有良好的检测能力,有些实验室的检测水平尚需提高。

Interlaboratory data comparison is one of the effective means to judge and monitor laboratory capability. National Quality Supervision and Inspection Center of Synthetic Rubber organized data comparison of bound styrene in styrene butadiene rubber . The results of comparison were processed with robust statistical techniques, and were calculated by Z ratio score, the statistical results showed that most of the laboratories had good detection ability, and the detection level of some laboratory needed to he improved.
