EQAS for immission measurement 2017

Summary of results: Competence in the measurement of ozone (O3) and nitrogen oxides (NO and NO2) was tested. The measurement results of all 12 participating organisations have been subjected to the same statistical evaluation methods as those foreseen for the European Reference Laboratories’ ring trials: according to the “Protocol for intercomparison exercises”, AQUILA document N37. Since February 2010, the Federal Environment Agency has regularly offered the operators of national and international air quality networks, as well as measuring instruments manufacturers, civil engineers and laboratories for immission measurements, the opportunity to check the measurement accuracy of their systems for different air pollutants in inter-laboratory tests.

结果综述：本次测试针对臭氧（O3）与氮氧化物（NO、NO2）的检测能力开展。所有12家参与机构的检测结果，均采用与欧洲参考实验室循环比对试验所预设的统一统计评估方法进行处理，该方法依据《比对试验规程》（AQUILA文件N37）制定。自2010年2月起，联邦环境署定期面向各国及国际空气质量监测网络运维方、检测仪器制造商、土木工程师以及环境浓度检测实验室提供实验室间比对试验参与机会，以核验其针对各类空气污染物的检测系统的测量精度。
