BS EN ISO 17138:2025 - TC

This standard BS EN ISO 17138:2025 - TC Tracked Changes. Fine ceramics (advanced ceramics, advanced technical ceramics). Mechanical properties of ceramic composites at room temperature. Determination of flexural strength is classified in these ICS categories:

• 81.060.30 Advanced ceramics

This document specifies a test method for the determination of the flexural strength of ceramic matrix composite materials with continuous fibre reinforcement, under three-point or four-point bend at room temperature. This document is applicable to all ceramic matrix composites with a continuous fibre reinforcement, unidirectional (1D), bidirectional (2D), and tridirectional xD with (2 < x ? 3) as defined in ISO 19634, loaded along one principal axis of reinforcement.
