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 to 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.
