Abstract：In China,the spark discharge atomic emission spectrometry widely uses type standardization for method calibration. In foreign countries, however, there are few relevant discussions about this method in standards and documents. There are two ways of calibration in type standardization, i.e., translation correction and rotation correction, but it is rarely reported that which one is more reasonable. The default setting of type standardization in foreign equipment gives priority to the rotation correction, but it is not clear about the optimal correction in relevant domestic standards. Moreover, the rationality of this default setting needs to be further discussed. Standard samples of low alloy steel (20CrNi2Mo and R407) and stainless steel (317L and 0Cr18Ni9) were selected. The relevant domestic standards were cited. The critical difference of trueness was used as judgment criteria. The trueness of data in translation correction and rotation correction was simulated under the conditions of "very close" and "close" between the standardized type samples and the samples to be tested. Through analyzing the statistical data, the analyzing results of translation correction could meet the requirements, while some elements did not meet the requirements when the rotation correction results were under the condition of "close". Based on the analysis of the element content range and precision data in relevant national standards, by calculating the maximum allowable bias and plotting the curve, the following conclusions were obtained: on the premise of meeting the control points of type standardization in the text, the analysis setting was more suitable for the translation correction.
