29、 ceramic-ceramic, ceramic-metal, and ceramic-glass joining loaded in the constant amplitude at room temperature. Procedures for test piece preparation, test modes and rates (load rate or displacement), data collection and reporting procedures are given.This document applies primarily to ceramic mate
30、rials, including monolithic fine ceramics and whisker-, fibre- or particle-reinforced ceramic composites. This test method can be used for material research, quality control, and characterization and design data-generation purposes.2 Normative referencesThe following documents are referred to in the
