能量色散X射线荧光光谱仪(EDXRF)广泛应用于电子电气产品中有害物质和其它材料中金属元素的检测.针对该仪器计量检测规范的缺失,结合其实际检测要求,提出了该仪器的校准方法,包括仪器的外观检查、线性误差、重复性、安全指标等基本的计量技术指标,并详细阐述了EDXRF线性误差测量不确定度评定的方法.%Energy dispersive X-ray fluorescence spectrometers (EDXRF) are widely used for determination of certain hazardous substances in electrical and electronic equipment and metal elements in other materials. Aiming at the lack of the measurement specifications and the actual test requirement of the EDXRF, calibration items and methods were proposed, including visual inspection, linear error, repeatability and safety performance. Meanwhile, the uncertainty evaluation of linear error was described in detail.
