纺织品中4-氨基偶氮苯的测定能力验证分析

摘要

Proficiency Testing Program for Determination of 4-aminozaobenzene in Textile(P00012-2011-T 07) was organized strictly according to operation of proficiency testing program. Test results from participants were evaluated by Robust analysis, the assigned value of sample was 54.8 mg/kg, the Norm Inter-Quartile Range (NIQR) was 6.894 1 mg/kg. A total of 61 laboratories from 12 provinces or autonomous regions enrolled in this program, performance of each participant was evaluated by means of Z-score, the percentage of satisfactory performance was 86.9%.%“P00012-2011-T07纺织品中禁用偶氮染料的测定(测试项目:4-氨基偶氮苯)”能力验证严格按照能力验证计划运作要求实施,并采用稳健统计法对测试结果进行统计,测试样品指定值为54.8 mg/kg,标准化四分位距(NIQR)为6.8941 mg/kg.共有12个省市、自治区的61家实验室参加本次能力验证,采用Z比分数对各实验室结果进行评价,结果满意率为86.9％.
