Routine method for analysis of high alloy steel by X-ray fluorescence spectrometry (XRF) by using a near by technique not-eligible The purpose of these tests1 Scope 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 as the unknown sample. The method is applicable to elements within the concentration ranges according to Table 1: Table 1 Concentration ranges Element
