This document specifies the conditions for determination of the stress-rupture time diagram of
continuous fibre-reinforced ceramic matrix composites (including carbon fibre-reinforced carbon
matrix composite) at high temperature in air, vacuum and inert gas atmospheres under constant tensile
loading.
This document applies to all ceramic matrix composites with 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
antioxidation coating.
NOTE 2 Since the main purpose of the test is to obtain the stress-rupture time data, the deformation
measurement is not mandatory.
