适用范围：This European Standard specifies the conditions for the determination of constant-amplitude of load or strainin uniaxial tension/tension or in uniaxial tension/compression cyclic fatigue properties of ceramic matrixcomposite materials (CMCs) with fibre reinforcement for temperature up to 1 700 °C in air at atmosphericpressure.This European Standard applies to all ceramic matrix composites with fibre reinforcement, unidirectional (1D),bi-directional (2D), and tri-directional (xD, where 2 < x ≤ 3).The purpose of this European Standard is to determine the behaviour of CMC when subjected to mechanicalfatigue and oxidation simultaneously. Tests for the determination of fatigue properties at high temperature ininert atmospheres differ from those in oxidative atmospheres. Contrary to an inert atmosphere, damage in anoxidative atmosphere accumulates due to the influence of purely mechanical fatigue and to chemical effects ofthe material’s oxidation.
