[中文适用范围]： 测试按以下程序进行：将样品在(105±2)℃的烘箱中干燥，使干燥的样品通过筛子并将其转移至量筒，但不形成气穴。 钢瓶和样品的称重。 将圆筒放入捣固体积计中，并以大约 1250 转的步长进行捣固，直到连续两次捣固步骤之间的差异小于 2 ml。 结果的计算。 - 取消并取代 ISO 建议 ISO/R 787/11-1970。 [外文原描述]： The test is carried out by the following procedure: drying of the sample in the oven at (105 2) °C, passing the dried sample through the sieve and transferring it of the graduated measuring cylinder, but so that no air pockets are formed. Weighing of the cylinder and of the sample. Placing of the cylinder in the tamping volumeter and tamping it in steps of approximately 1250 revolutions until the difference between two successive steps of tamping is less than 2 ml. Calculation of results. - Cancels and replaces ISO Recommendation ISO/R 787/11-1970.
