摘　　要：铜合金相较于低合金钢,元素种类较多、含量较高,元素间的干扰、自吸现象较复杂,使得检测中标准物质与被测样成分的一致性要求更为严格。《YS/T 482—2022铜及铜合金分析方法火花放电原子发射光谱法》中对于控制样品的定义是与分析样品具有相近的化学成分和组织结构,且有准确赋值的均匀样品,可以用于类型标准化修正。但并无明确定义何为相近的化学成分。根据直读光谱仪的使用特点,结合不同铜合金分类以及实际工作中铜合金分析元素的要求,探讨了铜合金直读光谱仪的类型标准化方法,保证了检测数据的准确性。Compared with low-alloy steel,copper alloys have more types and higher contents of elements,and the interference and self absorption phenomena between elements are more complex,which makes the consistency requirements between the standard substance and the tested sample composition more stringent in testing.The definition of control sample in YS/T482-2022 Methods for Analysis of Copper and Copper Alloys-Spark Discharge Atomic Emission Spectroscopy is a uniform sample with similar chemical composition and microstructure to the analyzed sample,and accurate assignment,which can be used for type standardization correction.But there is no clear definition of what constitutes similar chemical components.Based on the usage characteristics of direct reading spectrometers,combined with the classification of different copper alloys and the requirements for analyzing elements in copper alloys in practical work,this paper explores the standardization method of copper alloy direct reading spectrometers to ensure the accuracy of detection data.
