该方法用于通过压汞测定材料的孔径分布和孔面积。还测定了总孔口体积（侵入体积）、总孔隙面积、体积（块）密度和表观（骨架）密度。在413700 kPa（60000 psia）的最大压力下，填充0.003µm的小孔。该方法适用于在分析过程中获得的压力下基本不可压缩的材料。样品还必须不润湿，不与汞发生反应，且不得大于直径为25 mm、长度为25 mm的右圆柱体。

This method is for determining the pore size distribution and pore area of materials by mercury intrusion. Total port volume (intrusion volume), total pore area, bulk (piece) density and apparent (skeletal) density are also determined. At the maximum pressure of 413,700 kPa (60,000 psia) pores as small as 0.003 µm are filled. This method is applicable to materials which are essentially non-compressible at the pressures attained during analysis. The sample must also be non-wetting and non-reactive with mercury, and not larger than a right circular cylinder having 25-mm diameter with a length of 25-mm.
