ISO 14704:2016规定了一种在室温下测定整体细陶瓷和晶须或颗粒增强陶瓷复合材料弯曲强度的试验方法，适用于粒度小于200μm的材料。该试验方法可用于材料开发、质量控制、表征和设计数据生成目的。 注:由于断裂是由拉伸应力引起的，考虑到试验体积和威布尔统计的影响，弯曲强度数据可用于计算单轴拉伸强度。因此，弯曲强度通常被用来代替单轴拉伸强度。

ISO 14704:2016 specifies a test method for determining the flexural strength of monolithic fine ceramics, and whisker- or particulate-reinforced ceramic composites, at room temperature and applies to materials with grain size less than 200 μm. This test method may be used for materials development, quality control, characterization and design data-generation purposes. NOTE Since fracture is due to tensile stress, flexural strength data can be used to calculate a uniaxial tensile strength considering the effect of the tested volume and Weibull-statistics. So, flexural strength is often used in substitute for uniaxial tensile strength.
