摘　　要：目的建立现场检测工作中室内桌面照度测量不确定度评定的方法,对不确定度分量进行评定,计算出扩展不确定度值。方法根据《测量不确定度评定与表示(JJF 1059.1-2012)》和《公共场所卫生检验方法第1部分:物理因素(GB18204.1-2013)》的方法,对现场测量公共场所(候诊室)室内桌面照度值的各不确定度分量进行分析和计算,最终合成标准不确定度。结果本例用照度计法对某候诊室室内照度进行测量结果为:(225±10.74)lx,扩展不确定度为10.74 lx,其中采样高度是最大不确定度分量。结论该评定方法可用于现场检测中照度值测量的不确定度评定。Objectives A method was established to evaluating the uncertainty of indoor desktop illuminance measurement in field testing, to evaluate the uncertainty component, and to calculate the expanded uncertainty value. Methods According to the method of 《Evaluation and Expression of Measurement Uncertainty(JJF 1059.1-2012) 》 and 《Public Place Sanitary Inspection Method Part1:Physical Factors(GB 18204.1-2013)》,the uncertainty components of the on-site measurement of the indoor desktop illuminance value in public places(waiting room) were analyzed and calculated,standard uncertainty was composited finally. Results In this example,the indoor illuminance of a waiting room was measured by the illuminance meter method. The result was:(225 ± 10.74) lx,and the expanded uncertainty was 10.74 lx, where the sampling height was the largest uncertainty component. Conclusion This evaluation method can be used for the uncertainty evaluation of the illuminance value measurement in the field test.
