General methods of test for pigments and extenders - Part 11: Determination of tamped volume and apparent density after tamping (ISO 787-11:1981)

Scope

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.
