适用范围:This European Standard specifies a procedure on how to improve the performance of a routine XRF method,already in use for analysis of high alloy steels, by using a ”near by technique”.The ”near by technique” requires at least one target sample (preferable a CRM) of a similar composition asthe unknown sample.The method is applicable to analysis of either chill-cast or wrought samples having a diameter of at least25 mm and with a carbon concentration of less than 0,3 % (see NOTE). Other elements should have aconcentration below 0,2 %.NOTE High carbon concentrations, in combination with high Mo and Cr concentrations, could have undesirablestructural effects on the sample and could affect the determination of phosphorus and chromium, in particular.Matrix effects exist between the elements listed. To compensate for those inter-element effects, mathematicalcorrections shall be applied. A variety of computer programs for corrections is commonly used and included inthe software package from the manufacturers.
