本文件规定了测定铝生产中所用含碳产品表观密度的尺寸方法。 该方法适用于具有简单或定义明确的几何形状（例如圆柱形、矩形平行六面体或立方体）和光滑表面轮廓的样品。测量精度受到取样设备（即钻孔机和锯木机）的强烈影响。

This document specifies a dimensions method for the determination of the apparent density of carbonaceous products used in the production of aluminium. This method is applicable to samples with a simple or well-defined geometry (for example cylindrical, rectangular parallelepipedical or cubic) and a smooth surface profile. The accuracy of measurement is strongly influenced by the equipment used for sampling, i.e. the drilling and sawing machines.
