摘　　要：在实际生产应用中,火花放电原子发射光谱法广泛应用于线材的日常检验。而线材的规格种类繁多,若每个牌号每种规格都进行类型标准化不仅影响分析效率,而且会提高分析成本。实验针对小规格线材,分别使用φ6.60mm、φ5.42mm、φ4.22mm、φ3.02mm共4种类型标准化样品(以下简称类标)分析14种不同规格的待测线材,按照标准要求进行精密度和正确度的验证,开展了将火花放电原子发射光谱法类标按直径进行归并的可行性研究。结果表明,φ6.60mm的类标可以满足φ5.82mm~φ7.40mm样品的准确分析;φ5.42mm的类标可以满足φ5.02mm~φ5.82mm样品的准确分析;φ4.22mm的类标可以满足φ4.22mm~φ4.60mm样品的准确分析;φ4.22mm以下的线材只能进行相应规格的类型标准化。Spark discharge atomic emission spectrometry was widely used in the daily inspection of wire rods in the practical production and application.However,since there were many kinds of wire rods,the type standardization of each brand and each specification would not only influence the analysis efficiency,but also increase the analysis cost.Four types of standardized samples(hereinafter referred to as type standard)of φ6.60 mm,φ5.42 mm,φ4.22 mm and φ3.02 mm were used to analyze 14 different specifications of wire to be tested for small size wire rods.The precision and accuracy were verified according to the standard requirements.The feasibility study of merging the class standard of spark discharge atomic emission spectrometry by diameter was conducted.The results showed that:the type standard of φ6.60 mm could meet the requirements of accurate analysis of φ5.82 mm-φ7.40 mm samples;the type standard of φ5.42 mm could meet the requirements of accurate analysis of φ5.02 mm-φ5.82 mm samples;the type standard of φ4.22 mm could meet the requirements of accurate analysis of φ4.22 mm-φ4.60 mm samples;for the wire rod samples below φ4.22 mm,the type standardization of corresponding specification should be performed.
