Fine ceramics (advanced ceramics, advanced technical ceramics) - Ceramic composites - Determination of the degree of misalignment in uniaxial mechanical tests (ISO 17161:2014)
ISO 17161:2014 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.
ISO 17161:2014 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.
Hochleistungskeramik - Keramische Verbundwerkstoffe - Bestimmung der Fluchtungsfehler bei mechanischen Prüfungen mit einachsiger Beanspruchung (ISO 17161:2014)
Diese Internationale Norm beschreibt ein Verfahren:
— zur Verifizierung der Fluchtungsfehler des Krafteinleitungssystems einer Prüfmaschine, indem ein Referenzprobekörper gleichmäßig auf Zug oder Druck beansprucht wird; und
— um Hinweise zu Fehlern zu liefern, z. B. Torsions- und Biegefehler, um diese zu korrigieren.
Diese Internationale Norm ist nicht vorgesehen, um eine quantitative und zulässige Grenze anzugeben vor der Prüfung von Verbundwerkstoffen mit keramischer Matrix und unidirektionaler (1D), bidirektionaler (2D) sowie mehrdirektionaler (xD, mit 2 < x ≤ 3) Faserverstärkung, die entlang einer der Verstärkungshauptachsen beansprucht werden. Diese Grenze hängt von der Empfindlichkeit des jeweiligen Verbundwerkstoffes gegenüber den Fluchtungsfehlern ab.
ANMERKUNG 1 Diese Grenze wird zwischen Prüfstelle und Auftraggeber vereinbart.
ANMERKUNG 2 Monolithische Keramikwerkstoffe sind gegenüber Fluchtungsfehlern sehr empfindlich, während Verbundwerkstoffe mit keramischer Matrix (en: ceramic matrix composite, CMC) im Allgemeinen eine nur mäßige Empfindlichkeit aufweisen.
Céramiques techniques - Céramiques composites - Détermination du degré de non-alignement lors des essais mécaniques uniaxiaux (ISO 17161:2014)
L'ISO 17161:2014 décrit une procédure pour vérifier le degré de non-alignement du système de mise en charge des machines d'essai au moyen d'une éprouvette de référence soumise à un chargement uniforme de traction ou de compression et pour donner des indications afin de corriger des défauts tels que la torsion et la flexion.
L'ISO 17161:2014 n'est pas conçue pour fournir une limite quantitative acceptable avant les essais sur les composites à matrice céramique avec un renfort de fibres : unidirectionnel (1D), bidirectionnel (2D) et tridirectionnel (xD, avec 2 < x £ 3) le long d'un axe principal de renforcement. Cette limite dépend de la sensibilité de chaque type de composite au défaut d'alignement.
Fina keramika (sodobna keramika, sodobna tehnična keramika) - Keramični kompoziti - Ugotavljanje stopnje neporavnanosti pri enoosnih mehanskih preskusih (ISO 17161:2014)
Ta mednarodni standard opisuje postopek
– za preverjanje stopnje neporavnanosti vozička za nalaganje preskusnih strojev z uporabo referenčnega preskusnega primerka, enotno naloženega v raztezanje ali v stiskanje, in – za podajanje indikacij z namenom odpravljanja pomanjkljivosti, kot sta torzija in zvijanje. Ta mednarodni standard ni namenjen za zagotavljanje količinske in sprejemljive omejitve pred preskušanjem keramičnih matričnih kompozitov z ojačitvijo vlaken: enosmerno (1D), dvosmerno (2D) in trismerno (xD, z 2 < x ≤ 3), naloženih vzdolž ene glavne osi ojačitve. Ta omejitev je odvisna od občutljivosti posamezne vrste kompozita na učinek neporavnanosti.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

Fine ceramics (advanced ceramics, advanced technical
ceramics) — Ceramic composites — Determination of the
degree of misalignment in uniaxial mechanical tests
1 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 comp
