DIN EN 12789:2003-01

This document specifies the conditions for determination of the flexural strength of ceramic matrix composite materials with continuous fibre reinforcement under three-point or four-point bending for temperatures up to 1700 °C in air at atmospheric pressure. It applies to all ceramic matrix composites with a continuous fibre reinforcement, unidirectional (1D), bidirectional (2D), and tridirectional (xD, with 2 < × 3), loaded along one principal axis of reinforcement.
