Chemical analysis of magnesite and dolomite refractory products (alternative to the X-ray fluorescence method). Flame atomic absorption spectrophotometry (FAAS) and inductively coupled plasma atomic emission spectrometry (ICP-AES) | Status: Current, Confirmed

1 Scope This part of ISO 10058 specifies atomic absorption spectrometry (AAS) and inductively coupled plasma atomic emission spectrometry (ICP-AES) methods for the chemical analysis of magnesite and dolomite refractory products and raw materials. It is applicable to components within the ranges of determination given in Table 1. Table 1 — Range of determination (percentage by mass) Component Range Component Range
