Fine ceramics (advanced ceramics, advanced technical ceramics) - Ceramic composites - Determination of the degree of misalignment in uniaxial mechanical tests (ISO 17161:2014)
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
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.
