ISO 17161:2014 PDF

Scope: 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. NOTE 1 This limit is to be defined between the testing establishment and the customer. NOTE 2 Monolithic ceramics are very sensitive to misalignment defects while CMCs (ceramic matrix composite) in general are moderately sensitive to them.
