标准范围
ISO 8894的这一部分描述了用于测定非碳质介电耐火产品和材料的热导率的热线法（“交叉阵列”和“电阻温度计”）。这些方法适用于热导率值小于1.5 W/m × K（“交叉阵列”）和小于15 W/m × K（“电阻温度计”）以及热扩散率值小于5 × 10-6m2/s的致密和绝缘耐火材料（成型产品、耐火浇注料、塑料耐火材料、捣打混合物、粉末或粒状材料）。
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.
