- Version / remarks:
- The above information referes to the information from the manufacturer of the Jolting Volumeter STAV II (J. Engelsmann AG, Germany).
- Principles of method if other than guideline:
- The tapped density is an increased bulk density of the powder after a specified compaction process. The tapped density is obtained by mechanically tapping a graduated measuring cylinder containing the powder sample. After observing the initial powder volume and mass, the cylinder is mechanically tapped. The tapped density of the silica powder was measured by placing a defined amount of the powder into a 100ml graduated cylinder, which was tapped 500 times using Jolting Volumeter STAV II (J. Engelsmann AG, Germany). The volume occupied by the powder was then read and the density calculated based on the mass to volume ratio.
- GLP compliance:
- no
- Type of method:
- other: See "Remarks"
- Remarks:
- The tapped density of the silica powder was measured by placing a defined amount of the powder into a 100 ml graduated cylinder, which was tapped 500 times using Jolting Volumeter STAV II (J. Engelsmann AG, Germany).
