ISO 18754:2003规定了细陶瓷的表观固体密度、体积密度和表观孔隙率的测定方法。
该方法不适用于测定大于10%的表观孔隙率。对于孔隙率较高的材料,测量精度可能不令人满意。如果孔隙度小于0.5%,该方法也可能无法给出令人满意的开放孔隙度结果。
ISO 18754:2003 specifies a method for the determination of the apparent solid density, bulk density and apparent porosity of fine ceramics.
This method is not appropriate for the determination of an apparent porosity greater than 10 %. For materials with higher porosity, the accuracy of the measurement may not be satisfactory. The method may also not give satisfactory open porosity result if it is less than 0,5 %.
