Abstract��A lot of experiments have been done to solve the problem of the differences of the Rockwell hardness measurement between field test and laboratory test. The statistical analysis of the experimental results was made�� and the influences of various factors on the measurement results of Rockwell hardness were summarized and discussed. The experiment showed that the size of specimen was too large to ensure the flatness of detection surface�� which was a major cause of the high value of the product hardness measurement. And the treatment of grinding had little influence on the measurement results of specimen when its roughness had met the stand.Therefore�� the appropriate size should be selected to ensure the flatness in the preparation of Rockwell hardness specimen.
