Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 19 March 2013

- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Powder density (and volume) is determined by the use of a fully-automatic gas displacement pycnometer.
Tare the empty sample cup
- Fill the sample cup to at least 2/3 of the cup capacity with sample and record the weight
- Insert the filled sample cup into the cell chamber and close the cell chamber
