ASTM D5373 Standard Test Methods for Determination of Carbon, Hydrogen, and Nitrogen in Analysis Samples of Coal

    Introduction to ASTM D5373

    ASTM D5373 describes the standard test procedures for figuring out the carbon content of coke samples and the quantities of hydrogen, nitrogen, and carbon in coal samples. These techniques are essential for evaluating the content and quality of coal and coke, which are vital raw materials and fuels used in metallurgy and other industries, such as energy generation. ASTM D5373 describes how industries are able to guarantee regulatory compliance and make well-informed decisions regarding the acceptability of coal and coke for particular uses by accurately characterizing these elemental compositions. ASTM D5373 determines the elemental content of the samples, these test methods employ a variety of analytical techniques, such as spectroscopic and combustion procedures. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM D5373 tests for our clients.

    ASTM D5373 Test Method

    Direct Combustion Analysis Test Method

    Combustion of the sampleASTM D5373 uses direct combustion of the sample in the furnace at a higher temperature in the range of 900 °C to 1350 °C according to the need for coal and coke.
    Quantitative analysis The process involves converting carbon, hydrogen, and nitrogen into their corresponding gases during combustion in an oxygen atmosphere, removing interference products, and reducing nitrogen oxides to N2.

    ASTM D5373 Test Specimens

    Specimen DetailASTM D5373 uses combustion vessels as a test specimen. In this practice, a furnace at higher temperatures is used to measure the quantity of carbon, hydrogen, and oxygen in coal and coke
    Specimen SizeThe sample size and preparation method for a test method should be homogenized and finely ground to ensure uniformity and accurate analysis.

    ASTM D5373 Test Result

    ASTM D5373 effectively tests the quantitative measurement of elements in samples of coal and coke. The percentages of carbon, hydrogen, and nitrogen are measured in the sample of coal, and the total percentage of carbon is measured in the sample of coke.

    ASTM D5373 Related Tests

    ASTM D5373 is related to tests, including ASTM D3173, which tests moisture in coal and coke analysis samples, and ASTM D7582, which is used for proximate analysis of coal and coke by macro thermogravimetric analysis.
