Abstract：In order to improve the accuracy of plastometer indices determination of bituminous coal, and combining with the testing principles and method, the influencing factors in experimental coal samples, equipment and operation process were analyzed, some precautions and treatment suggestions were proposed from aspects such as experimental coal samples, coal cup and probe, silicon carbide rod and furnace brick, temperature control system and thermocouples, carbon black interference treatment, determination requirements of different curve types and curve drawing, so that the deviation among laboratories could be reduced, and the accurate and reliable analyzing results could be obtained.
