三点波束测试非常简单，对表面条件非常敏感。它似乎非常适合牙齿瓷的评估，但样本制作很困难。在这项研究中，陶瓷标本上烧制铂箔已建成使用氧化铝前。结果显示了极好的样品一致性和重现性。在所研究的表面中，使用氧化锡涂覆的铂箔不会导致横向强度的增加。
The three-point beam test is simple and extremely sensitive to surface conditions. It appears to be ideally suited to the evaluation of dental porcelain, but specimen fabrication is difficult. In this study, specimens of porcelain fired on platinum foil have been constructed using an alumina former. The results showed excellent specimen consistency and reproducibility. Of the surfaces investigated, the use of tin-oxide-coated platinum foil did not result in an increase in transverse strength.
