Measurements were taken of the diameter and length of each part of commercial silver points of international standard of three companies (Kerr, Zipperer, Maillefer). measurements were compared with the specification in DIN Standard to determine the status of standardization. The results were as follows : 1. The total length specified in DIN Standard is 28+2 mm. Maillefer #15∿#40 were longer and the others were within the limits of DIN. Rather narrow variation were seen in the total length and effective length between pins of the same specification of each company. 2. In the comparison of d_1 of the three companies with that of DIN Standard, they were about the same diameter except for #40 of Kerr. 3. Kerr's approximated the tapering specification of DIN Standard. contrarily, Maillefer's were smallest. Kerr's and Zipperer's had the least variation in tapering.
