Abstract: A density calibration method by industrial CT was introduced, which was recommended by ASTM. An example was presented to demonstrate the feasibility and accuracy of the method under a 9MeV industrial CT. The method could be put into use in practical density measurement and in the performance test of an industrial CT.
