CEN/TS 15867:2009

This Technical Specification provides guidance on: -  verifying the degree of misalignment of the load train of test machines, using a reference test specimen uniformly loaded in tension or in compression; -  correcting for defects caused by, e.g. torsion and bending. This document is not intended to provide a quantitative and acceptable limit before the testing of ceramic matrix composites with a fibre reinforcement: unidirectional (1D), bidirectional (2D) and tridirectional (xD, with 2 < x ≤ 3) loaded along one principle axis of reinforcement. This limit depends on the sensitivity of each type of composite to the misalignment defect.
