There is no standardized method in Japan for the estimation of impact strength for strengthened porcelain tableware. In many cases, a measurement is carried out by ASTM C368 using a pendulum formula impact tester. However, there are many unknown factors about statistical dispersion in impact strength values, and the relation between the number of tested samples and accuracy of measurement. In this experiment, the impact measurement was carried out using a large number of high strength porcelain tableware. The dispersion in impact strength values was confirmed to show a normal distribution statistics, and the relation between the number of samples and measurement accuracy was discussed. Furthermore, it was revealed that the impact strength value was also influenced by the shape and weight of the impact hammer head.
