摘　　要：目的提供外部质量控制考核手段,评价获证实验室室内空气总挥发性有机物(TVOCs)检测能力。方法单个水平样品设计,采用稳健统计方法结合专家评议对实验室能力进行评价。结果北京地区48个室内空气质量检测机构参加了本次比对,获得满意结果的有39家,占参加单位的81.2%,初测结果不合格的有9家,占参加单位的18.8%。结论北京地区获资质认定的室内空气质量检测机构,大多数具有TVOCs检测能力。Objectives To provide methods of external quality control in order to evaluate the capability of certified labs in Beijing on detecting total volatile organic compounds （TVOCs） in indoor air. Methods The labs participating in the proficiency testing （PT） were divided into 3 groups, and 16 labs in each group. The capability of labs was evaluated by Robust Star and Expert （robust statistical methods combined with expert comments）. Results The results of 39 labs （ 81.2% ） were satisfactory, but the results of 9 labs （ 18. 8% ） were dissatisfactory. Conclusion The competence of most labs participating in the PT of detecting TVOCs in indoor air was good.
