适用范围：This Technical Report aims to facilitate reference to the available international standard method(s) for the determination of required element(s) in steel and iron.In this Technical Report, field of application, method of determination (principle) and precision (see notes) of each standard are stated.NOTES1 Two of the three determinations were carried out under repeatability conditions as defmed in ISO 5725, i.e. one operator, same apparatus, identical operating conditions (same calibration) and a minimum period of time.2 The third determination was carried out at a different time (different day) by the same operator as in note 1 above using the same apparatus with a new calibration.3 From the results obtained on Day 1 the repeatability (r) and reproducibility (R) were calculated using the procedure specified in ISO 5725. From the first result obtained on Day 1 and the result obtained on Day 2, the within-laboratory reproducibility (Rw) was calculated.
