标准摘要
ISO 20203:2005 describes a test method for the determination of the mean crystallite height of a representative, pulverized sample of calcined petroleum coke by interpretation of an X-ray diffraction pattern produced through conventional X-ray scanning techniques. ISO 20203:2005 applies to carbonaceous materials used in the production of aluminium.
