Scope
This standard specifies the method for determining the content of coke ash components by X-ray fluorescence spectrometry. This standard is applicable to the determination of ash components in coke (metallurgical coke, semi-coke, coke for ferroalloys, etc.) and coal. The measurement ranges (mass fractions) of each component are shown in Table 1.
