CNAS-CL01:2006《检测和校准实验室能力认可准则》(ISO/IEC17025:2005)中的规定“检测实验室应具有并应用评定不确定度的程序”[1]。依据JJF105-1999《测量不确定度评定与表示》[2],我们结合实际工作,建立了火焰原子吸收光谱法测定工作场所空气中钠的不确定度评定方法[3]。旨在
CNAS-CL01: 2006 “Testing and Calibration Laboratory Competency Guidelines” (ISO / IEC17025: 2005), “Testing laboratories should have and apply procedures for assessing uncertainty” [1]. According to JJF105-1999 “Evaluation and Expression of Measurement Uncertainty” [2], we established the method of flame atomic absorption spectrometry to determine the uncertainty of sodium in the air of workplace [3].
