该欧洲标准描述了确定致密成型耐火材料产品加热尺寸永久变化的三种方法。注意:该方法可应用于对氧化敏感的材料。然而，这些材料中的一些可以在测试期间受到影响，使得尺寸变化的测量不可能执行到所需的精度

This European standard describes three methods for the determination of the permanent change in dimensions on heating of dense shaped refractory products. Note: The method can be applied to materials sensitive to oxidation. However, some of these materials can be affected during the test in such a way as to make the measurement of the dimensional changes impossible to carry out to the required accuracy.
