Abstract
Statistical analysis of the strength of porcelain tableware is very important; however, there are few reports on impact strength of product wares. In this research, the impact strength of commercial reinforced porcelain plates were measured using pendulum-type impact tester based on an ASTM C368. Statistical dispersion of the impact strength was analyzed for many types of reinforced porcelain tableware. The mathematical distribution of the impact strength could be estimated with a normal distribution. The statistical dispersion of the impact strength showed the same tendencies, regardless of the tableware shape or the mean impact strength value. The median coefficient of variation, (Standard deviation)/(Mean impact strength), was 0.118. Details of the destruction of reinforced porcelain tableware were studied by observations of the fractured surfaces.
