DIN EN ISO 17161:2016-10

This International Standard 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 International Standard 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 principal axis of reinforcement. This limit depends on the sensitivity of each type of composite to the misalignment defect.
