Abstract

This article dealt with significant difference in S_D values due to size variation of loading head dimension. There are two major errors in loading head dimension; one is in diameter (D) of loading head, and another is in radius (r) of round cut at the bottom edge. If the D is smaller than standard size, the S_D was found to be resulted in larger values, and if r is smaller than normal size, the S_D was found to be also greater values. The acceptable D and r are suggested to be 40 ± 0.05 mm and r = 10 ± 0.03 mm, respectively.
