适用范围：This International Standard applies to carbonaceous materials for the production of aluminium. This International Standard describes a test method which covers the analysis for commonly determined trace metals in test specimens of raw and calcined petroleum coke by inductively coupled plasma atomic emission spectroscopy. It can also be applied to other heat-treated carbonaceous materials e.g. coal-tar pitch coke, anthracite. Elements to which this test method applies are listed in Table 1. Detection limits, sensitivity, and optimum ranges of the metals will vary with the matrices and model of spectrometer. This test method is applicable only to samples containing less than a mass fraction of 1 % ash. Elements present at concentrations above the upper limit of the working ranges can be determined with additional, appropriate dilutions.
