Advanced technical ceramics - Mechanical properties of ceramic composites at high temperature in air at atmospheric pressure - Determination of compression properties

Scope

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.
