稳健统计技术在纺织品pH检测能力验证中的应用

摘要

介绍了28家试验室参加纺织品pH检测能力验证活动的情况,选择从市场上购买的纺织面料作为测试样本,采用F 检验对样本的均匀性进行检验,并用稳健统计技术对试验结果进行了分析.根据Z比分数值对试验室的表现进行评估,最后列出了能力验证活动中不合格的行为,并提出了改进检测质量的技术建议.%The proficiency test with participation of 28 laboratories was introduced in this paper. The textile fabric bought from the market was used as test specimen. The specimen uniformity was examined with F statistical , and the test results were analyzed with robust statistical technique. The test ability of each laboratory was assessed based on its Z score. Some unqualified behaviors during proficiency test were listed at last and some professional advices were provided to promote test quality.
