摘　　要：目的进一步考查规范北京地区室内空气质量检测机构的检测工作,以保证检测结果的准确性和公正性。方法59户检测机构用国家标准方法对氨和苯双浓度样品进行比对测定,采用检测比对方案进行统计,采用稳健Z比分数方法评价检测结果。结果氨和苯均为满意结果的实验室有28户,占实验室总数的47.5%。氨和苯检测结果均不满意的实验室有3户,1项检测结果不满意、1项检测结果有问题的实验室有6户,1项检测结果不满意、1项检测结果满意的实验室有12户,1项检测结果有问题、1项检测结果满意的实验室有10户。结论参加该次比对实验的室内空气质量检测机构在日常检测工作中仍然存在一定问题。各级主管部门需进一步加强对检测机构的监督管理,规范检测市场,促进检测机构不断提高自身检测工作质量和水平。Objective To evaluate the capacity of air quality test of indoor air quality test agencies in Beijing. Methods 59 laboratories participated the evaluation. The standard reference （SRF） material, ammonia and benzene, were used as the test items and the national standard methods were used in the determination, the capacity evaluation was clone by comparing the test values and Robust Z-Score. Results 28 laboratories （47.5%） presented a satisfactory result for both ammonia and benzene determination, 3 gave an unsatisfactory result for both items, 28 showed an unsatisfactory result or a result with some error in ahernativel item. Conclusion In the present study, only 47.5% of the investigated laboratories are satisfied. There are still some problems in the capacity of air quality test of test agencies in Beijing and the test capacity need to be improved.
