标准摘要
[中文适用范围]： 本国际标准规定了一种测试方法，用于测定精细陶瓷微观结构中体积内的宏观异质性（macro-heterogeneities）大于一定尺寸的情况，这些异质性对材料的力学强度性质有显著影响。该方法仅限于孔隙率小于10 vol%且以薄试样形式对可见光透明的精细陶瓷。 [外文原描述]： ISO 18550:2016 specifies a test method for determining macro-heterogeneities within the microstructure of fine ceramics that are above a certain size within the volume of the material and affect materials mechanical strength properties. This method is limited to fine ceramics with a porosity of less than 10 vol% and that are transparent for visible light in the form of a thin specimen.
