This part of this European Standard describes a method for determination of compression properties of ceramic matrix composite materials with continuous fibre reinforcement at room temperature. This method applies to all ceramic matrix composites with a continuous fibre reinforcement, unidirectional (1D), bidirectional (2D), and tridirectional (xD, with 2 < x <=3) as defined in ENV 13233, loaded along one principal axis of reinforcement. Two cases are distinguished: - compression between platens; - compression using grips.
