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.
The method is applicable to analysis of either chill-cast or wrought samples having a diameter of at least 25 mm and with a carbon concentration of less than 0,3 % (see NOTE). Other elements should have a concentration below 0,2 %.
