This part of ISO 8894 describes the hot-wire methods (“cross-array” and “resistance thermometer”) for the determination of the thermal conductivity of non-carbonaceous, dielectric refractory products and materials. This 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 x 10-6 m2/s.
Abstract
Overview
EN ISO 8894-1:2010 (ISO 8894-1:2010) specifies hot-wire methods for determining the thermal conductivity of non‑carbonaceous, dielectric refractory materials. It covers two dynamic hot‑wire techniques - the cross‑array method and the resistance‑thermometer method - applicable to dense and insulating refractories (shaped products, castables, plastics, ramming mixes, powders/granulates). Measurements can be made up to 1 250 °C (subject to the material’s service limit or dielectric behaviour).
Keywords: ISO 8894-1:2010, EN ISO 8894-1, refractory materials, thermal conductivity, hot-wire methods, cross-array, resistance thermometer.
