This European Standard EN 12291 specifies the conditions for determination of compression properties of ceramic matrix composite materials with continuous fibre reinforcement for temperatures up to 1 700 °C in air at atmospheric pressure.
This European Standard applies to all ceramic matrix composites with a continuous fibre reinforcement, unidirectional (1D), bidirectional (2D), and tridirectional (xD, with 2 < x < 3), loaded along one principal axis of reinforcement.
NOTE 1 In most cases, ceramic matrix composites to be used at high temperature in air are coated with an anti oxidation coating.
NOTE 2 The purpose of this European standard is to determine the compression properties of a material when it is placed under an oxidizing environment but not to measure material oxidation.
Two cases are distinguished:
a) compression between platens
b) compression using grips.
