精细陶瓷 (高级陶瓷, 高级工业陶瓷). 测定陶瓷管和环件弹性模量及弯曲强度的试验方法

[中文适用范围]： 本国际标准规定了在环境温度下通过开环（split ring）片段的压缩试验测定陶瓷管或环的弹性模量和弯曲强度的测试方法。该标准涵盖了测试样品的制备、测试模式、加载速率、数据收集以及报告程序的方法。本国际标准主要适用于陶瓷材料，包括单一精细陶瓷、玻璃、晶须或颗粒增强陶瓷复合材料，但不适用于纤维增强陶瓷复合材料。该测试方法可用于材料研究、质量控制以及表征和设计数据生成目的。 [外文原描述]： ISO 18558:2015 specifies the testing method for determining the elastic modulus and bending strength of ceramic tubes or rings at ambient temperature by the compression tests on split ring pieces. Methods for test piece preparation, test modes and load rates, data collection, and reporting procedures are addressed. This International Standard applies primary to the ceramic materials including monolithic fine ceramic, glass, whisker- or particulate reinforced ceramic composites, but not available for fibre reinforced ceramic composites. This test method may be used for material research, quality control, and characterization and design data generation purpose.
