标准摘要
[中文适用范围]： ISO 15379 的这一部分规定了一种方法，涵盖了铝生产中使用的阴极块材料中钠渗透导致的外部压力下线性膨胀的测定。 由于各向异性，块的线性膨胀取决于采样方向。 [外文原描述]： ISO 15379-2:2015 specifies a method that covers the determination of linear expansion under external pressure due to sodium penetration in cathode-block materials used in the production of aluminium. The linear expansion of the blocks depends on the sampling direction due to anisotropy.
英文名称Carbonaceous materials for the production of aluminium — Cathode block materials — Part 2: Determination of the expansion due to sodium penetration without application of pressure
