Feuerfeste Werkstoffe - Bestimmung der Wärmeleitfähigkeit - Teil 1: Heißdrahtverfahren (Kreuzverfahren und Widerstandsthermometer-Verfahren) (ISO 8894-1:2010); Deutsche Fassung EN ISO 8894-1:2010

Overview

This standard specifies the hot-wire methods ("cross-array" and "resistance thermometer") for the determination of the thermal conductivity of non-carbonaceous, dielectric refractory products and materials. These methods are applicable to dense and insulating refractories (shaped products, refractory castables, plastic refractories, ramming mixes, powdered or granular materials) with thermal conductivity values less than 1,5 W/m×K ("cross-array") and less than 15 W/m×K ("resistance thermometer") and thermal diffusivity values less than 5×10-6 m+2/s. Thermal conductivity values can be determined at a room temperature up to 1 250 °C. The maximum temperature of 1 250 °C can be reduced by the maximum service limit temperature of the refractory, or by the temperature at which the refractory is no longer dielectric. EN ISO 8894-1:2010 has been prepared by Technical Committee ISO/TC 33 "Refractories", in collaboration with Technical Committee CEN/TC 187 "Refractory products and materials", the secretariat of which is held by BSI (United Kingdom). At DIN the responsible German committee is Working Committee NA 062-02-57 AA "Ungeformte, dichte geformte und wärmedämmende feuerfeste Erzeugnisse und Werkstoffe" ("Unshaped, dense shaped and insulating refractory products and materials") of NMP.
