This standard specifies the sampling tool, sampling location, sampling quantity, sample size and precision of carbon materials. This standard applies to the collection and preparation of carbon material samples such as graphite electrodes, graphite anodes, graphite blocks, cathode carbon blocks, carbon electrodes, electric furnace carbon blocks, carbon paste, high-purity graphite products, and mesophase carbon microspheres.
