Annotation of standard text ČSN EN ISO 17138 (727505):

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.
This document is not intended to be used to obtain absolute values of strength for design purposes
