ISO 10545-23:2025

This document specifies a testing method for determining the elastic modulus of glazed and unglazed ceramic tiles, substrate and glaze layer at ambient temperature by three-point bending tests. This document also specifies procedures for test specimen preparation, test modes, load rates, data collection and reporting. This test method can be used for material research, quality control, characterization and design data-generation purposes of ceramic tiles with a plate shape. See Annex A for more information. This method is not applicable to the ceramic tiles with profiled structures from which the test specimen cannot be machined.
