标准摘要
[中文适用范围]： ISO 21078 的这一部分规定了使用酸萃取法测定添加到铝硅酸盐耐火材料中用作粘合剂成分的氧化硼（III）的化学分析程序。 本标准适用于三氧化二硼（质量分数）以下的耐火材料。 1% [外文原描述]： ISO 21078-2:2006 specifies procedures of chemical analysis for the determination of boron(III) oxide used as a binder component added to aluminosilicate refractories, using an acid extraction method. It is applicable for refractories containing less than 1 % (mass fraction) of boron(III) oxide.
