DIN CEN/TS 15867:2009-07

This Technical Specification describes a procedure to verify the degree of misalignment of the load train of the test machines using a reference test specimen uniformly loaded in tension or in compression and to give indications in order to correct defects such as 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.
