Fine ceramics (advanced ceramics, advanced technical ceramics) - Mechanical properties of ceramic composites at high temperature - Determination of tensile properties (ISO 14574:2013)

ISO 14574:2013 specifies the conditions for determination of tensile properties of ceramic matrix composite materials with continuous fibre reinforcement for temperatures up to 2 000 °C.
ISO 14574:2013 applies to all ceramic matrix composites with a continuous fibre reinforcement, unidirectional (1D), bi-directional (2D), and tri-directional (xD, with 2 < x ≤ 3), loaded along one principal axis of reinforcement.

Hochleistungskeramik - Mechanische Eigenschaften von keramischen Verbundwerkstoffen bei hoher Temperatur - Bestimmung der Eigenschaften unter Zug (ISO 14574:2013)

Diese Internationale Norm legt die Bedingungen zur Bestimmung der Eigenschaften von endlos-faserverstärkten keramischen Verbundwerkstoffen unter Zugbeanspruchung bei Temperaturen bis zu 2 000 °C fest.
ANMERKUNG 1   In den meisten Fällen sind die bei hoher Temperatur in Luft einzusetzenden Verbundwerkstoffe mit keramischer Matrix mit einer Deckschicht gegen Oxidation geschützt.
ANMERKUNG 2   Der Zweck dieser Internationalen Norm besteht darin, die Zugeigenschaften eines Werkstoffes in oxidierender Umgebung zu bestimmen, nicht aber die Oxidation des Werkstoffes zu messen.
Diese Internationale Norm gilt für alle endlosfaserverstärkten Verbundwerkstoffe mit keramischer Matrix mit unidirektionaler (1D), bidirektionaler (2D) und mehrdirektionaler (xD, mit 2 < x ≤ 3) Verstärkung mit der Beanspruchung längs zu einer der Hauptverstärkungsachsen.

Céramiques techniques - Propriétés mécaniques des céramiques composites à haute température - Détermination des caractéristiques en traction (ISO 14574:2013)

L'ISO 14574:2013 fixe les conditions de détermination des propriétés en traction des matériaux composites à matrice céramique et à renfort continu pour des températures allant jusqu'à 2 000 °C.
L'ISO 14574:2013 s'applique à tous les composites à matrice céramique à renfort continu, unidirectionnel (1D), bidirectionnel (2D), et tridirectionnel (xD, avec 2 < x ≤ 3) sollicités suivant un axe principal de renfort.

Fina keramika (sodobna keramika, sodobna tehnična keramika) - Mehanske lastnosti keramičnih kompozitov pri visoki temperaturi - Ugotavljanje nateznih lastnosti (ISO 14574:2013)

Ta mednarodni standard opredeljuje pogoje za določanje nateznih lastnosti keramičnih matričnih kompozitnih materialov pri temperaturah do 2000 °C. Ta mednarodni standard se uporablja za vse keramične matrične kompozitne materiale z neprekinjeno ojačitvijo vlaken, enosmerno (1D), dvosmerno (2D) in trismerno (xD, kjer je 2 < x ≤ 3), naloženih vzdolž ene glavne osi ojačitve.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
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.
ISO 14574 was prepared by Technical Committee ISO/TC 206, Fine ceramics.
