Advanced technical ceramic - Ceramic composites - Methods of test for reinforcements - Part 6: Determination of tensile properties of filaments at high temperature
This European Standard specifies the conditions for measurement of tensile properties of single filament of ceramic fibres at high temperatures in air or inert atmosphere (vacuum or controlled atmosphere). The method applies to continuous ceramic filaments taken from tows, yarns, staple fibre, braids and knitting, that have strain to fracture less or equal to 5 % and show linear elastic behaviour to fracture.
The method does not apply to testing for homogeneity of strength properties of fibres, nor does it assess the effects of volume under stress. Statistical aspects of fibre failure are not included.
Two methods are proposed depending on the temperature of the filament end:
Hot end method: this method allows determination of tensile strength, of Young's modulus and of the stress strain curve.
NOTE 1 Current experience with this technique is limited to 1 300 °C, because of the application temperature of ceramic glue.
Cold end method.
NOTE 2 This method is limited to 1 700 °C in air and 2 000 °C in inert atmosphere because of the limits of furnaces.
Hochleistungskeramik - Keramische Verbundwerkstoffe - Verfahren zur Prüfung der Faserverstärkungen - Teil 6: Bestimmung der Zugeigenschaften von Fasern bei hoher Temperatur
Diese Europäische Norm legt die Bedingungen fest, die für die Bestimmung der Zugeigenschaften einzelner Fäden keramischer Fasern bei hoher Temperatur in Luft oder inerter Atmosphäre (in Vakuum oder einer geregelten Atmosphäre) einzuhalten sind. Das Verfahren gilt für keramische Endlosfasern mit einer Bruchdehnung gleich oder kleiner als 5 % und mit linearem elastischem Verhalten bis zum Bruch, die
Fa¬serbündeln, Fäden, Stapelfasern, Geflechten und Gewirken entnommen werden.
Das Verfahren dient weder zur Überprüfung der Homogenität der Festigkeitseigenschaften der Fasern noch zur Beurteilung der Wirkungen, die von einem unter Spannung stehenden Volumen ausgehen. Statistische Aspekte des Faserbruchs werden nicht erfasst.
In Abhängigkeit von der Temperatur des Faserendes sind zwei Verfahren anwendbar:
- Verfahren mit erhitzten Probenenden: Mit diesem Verfahren sind die Zugfestigkeit, der Youngsche Elastizitätsmodul und die Spannungs Dehnungs Kurve zu bestimmen;.
ANMERKUNG 1 Für dieses Verfahren liegen wegen der maximalen Anwendungstemperatur des Keramikklebstoffs bisher nur Erfahrungen bis zu einer Temperaturgrenze von 1 300 °C vor.
- Verfahren mit kalten Probenenden
ANMERKUNG 2 Die Temperaturgrenzen für dieses Verfahren liegen bedingt durch die verfügbaren Öfen bei Tempera¬turen von 1 700 °C in Luft und 2 000 °C in inerter Atmosphäre.
Céramiques techniques avancées - Céramiques composites - Méthodes d'essai pour renforts - Partie 6 : Détermination des propriétés en traction du filament à haute température
La présente Norme européenne spécifie les conditions de mesure des propriétés en traction d'un filament individuel en fibres céramiques à hautes températures dans l'air ou sous atmosphère inerte (sous vide ou atmosphère contrôlée). La méthode s'applique à des filaments céramiques continus issus de mèches, fils, fibre discontinue, tresses et tricots ayant un allongement à la rupture inférieur ou égal à 5 % et montrant un comportement linéaire élastique jusqu'à la rupture.
La méthode ne permet pas de soumettre à essai l'homogénéité des propriétés de traction des fibres, elle ne permet pas plus d'évaluer les effets de volume sous contrainte. L'aspect statistique de la rupture des fibres n'est pas envisagé.
Deux méthodes sont proposées en fonction de la température de l'extrémité du filament :
Méthode avec mors chauds : cette méthode permet de déterminer la résistance en traction, le module de Young et la courbe contrainte-déformation.
NOTE 1 L'expérience actuelle acquise avec cette technique se limite à 1 300 °C du fait de la température d'application de la colle céramique.
Méthode avec mors froids.
NOTE 2 Cette méthode est limitée à 1 700 °C dans l'air et à 2 000 °C en atmosphère inerte du fait des limites des fours.

Overview
EN 1007-6:2007 is a CEN standard that defines test methods for determining the tensile properties of single ceramic filaments at high temperature. It applies to continuous ceramic filaments (from tows, yarns, staple fibre, braids and knitting) that show linear elastic behaviour to fracture and have strain-to-fracture ≤ 5%. Tests are performed in air or inert atmospheres (vacuum or controlled gas) and are intended to measure tensile strength, Young’s modulus and stress–strain behavior under elevated temperatures.
Key topics and technical requirements
- Scope and limitations
- Applies only to single-filament tensile tests at high temperature; does not address strength homogeneity, volume-under-stress effects, or statistical failure analysis.
- Filaments must be linear-elastic to fracture with strain ≤ 5%.
- Two test methods
- Hot end method - filament heated over its full length; enables determination of tensile strength, Young’s modulus and full stress–strain curve. Practical experience limited to ≈ 1 300 °C due to ceramic adhesive limits.
- Cold end method - only the central gauge section is heated; avoids high-temp adhesive issues and extends testing limits (up to ≈ 1 700 °C in air and 2 000 °C in inert atmospheres, limited by furnace capability).
- Test preparation and measurement
- Gauge length control: 25 mm specimens for force–displacement curves; 10 mm and 40 mm specimens for load-train compliance determination (tolerance ±1 mm).
- Minimum valid results: five tests at 25 mm; three additional tests at 10 mm and 40 mm for strain-related properties.
- Temperature uniformity requirement: variation within the gauge length ≤ 20 °C at test temperature.
- Equipment and accuracy: force measurement to EN ISO 7500-1 grade 1; displacement accuracy better than 1 µm; calibrated thermocouples or pyrometers (EN 60584 series).
- Data handling: force and displacement recorded simultaneously; elongation often derived via compliance correction.
- Environmental control
- Gastight chambers for inert atmosphere; vacuum levels must not destabilize filament material.
- Choice of gas and pressure depends on material and test temperature.
Applications and users
- Intended for manufacturers and developers of ceramic composites and advanced technical ceramics needing validated high-temperature filament data.
- Useful for:
- Materials scientists and R&D labs characterizing high-temp fibre behavior.
- Quality-control and certification labs performing tensile testing of ceramic fibres.
- Designers of high-temperature components (aerospace, automotive, energy, thermal protection) relying on filament mechanical data.
- Provides reproducible test protocols for comparing filament tensile strength, modulus and stress–strain response at elevated temperatures.

NOTE This is because some of the contributions to the load train compliance (for example the cement used for fixing the filament) may vary with temperature. Calculate the total compliance Ct for the tests at each of the gauge lengths from the inverse slope in the linear part of the force/cross-head displacement curve.
For each test, plot the total compliance Ct versus L0/A0. Perform a linear regression analysis of Ct versus L0/A0 and determine the load train compliance Cl from the intercept with the ordinate axis (Figure 3). SIST EN 1007-6:2009
