(Main)Methods of test for dense shaped refractory products - Part 15: Determination of thermal conductivity by the hot-wire (parallel) method
Methods of test for dense shaped refractory products - Part 15: Determination of thermal conductivity by the hot-wire (parallel) method
This part of EN 993 specifies a hot-wire (parallel) method for the determination of thermal conductivity of refractory products and materials. It is applicable to dense and insulating shaped products and to powdered or granular materials (see 7.2), for thermal conductivities of less than 25 W/m.K. The limits are imposed by the dimensions of the test pieces and higher thermal conductivities can be measured if larger pieces are used. Electrically conducting materials cannot be measured.
Prüfverfahren für dichte geformte feuerfeste Erzeugnisse -Teil 15: Bestimmung der Wärmeleitfähigkeit nach dem Heißdraht-(Parallel-) Verfahren
Dieser Teil von EN 993 legt ein Heißdraht-Verfahren (Paralleldraht-Verfahren)zur Bestimmung der Wärmeleitfähigkeit von feuerfesten Erzeugnissen und Werkstoffen fest. Diese Norm ist anwendbar auf dichte und zur Isolation dienende geformte Erzeugnisse sowie auf pulverförmiges oder körniges Probengut (siehe 7.2) mit einer Wärmeleitfähigkeit von kleiner als 25W/m x K. Die Grenzen sind durch di e Maße der Probekörper vorgegeben; höhere Wärmeleitfähigkeiten können bei Verwendung größerer Probekörper gemessen werden. Elektrisch leitende Werkstoffe können nicht gemessen werden.
Méthodes d'essai pour produits réfractaires façonnés denses - Partie 15: Détermination de la conductivité thermique par la méthode du fil chaud (parallèle)
La présente partie de la norme européenne EN 993 spécifie une méthode de détermination de la conductivité thermique des matériaux et produits réfractaires par la méthode du fil chaud (parallèle).Elles'applique aux produits façonnés denses et isolants, et aux matériaux pulvérulents (voir 7.2), pour des conductivités thermiques inférieures à 25 W/mK. Ces limites sont imposées par les dimensions des éprouvettes et des conductivités thermiques plus élevées peuvent être mesurées en utilisant de plus grandes éprouvettes. Les matériaux électriquement conducteurs ne peuvent pas être soumis à cette mesure.
