- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2013-01-29 to 2013-02-20
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: well documented GLP based study according to standard procedure
- Qualifier:
- according to guideline
- Guideline:
- other: CIPAC MT 169
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: SPR/BF/17/b
- Principles of method if other than guideline:
- The tap density was determined by measuring the exact volume of a certain amount (approx. 130grams) of the substance using a dropping box.The density then was calculated by dividing the exactly measured mass by the exactly measured volume.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: Dropping Box
- Key result
- Type:
- tap density
- Density:
- 0.656 other: g/ml
- Remarks on result:
- other: measurement was done at room temperature, no exact value is available
- Conclusions:
- Having applied the procedure according to the guideline CIPAC MT 169 for density determination of TC (Commercial grade of about 65%) using a dropping box, a tap density of 0.656 g/ml could be estimated.
- Executive summary:
The bulk density of TC (Commercial grade of about 65%) was determined according to the guideline CIPAC MT 169 using a dropping box. Hereby, the exact volume of an exact amount of the substance was measured. The pour density was then calculated by dividing the exactly measured mass of the substance by the exactly measured volume. Two replicates were performed. Overall, a tap density of 0.656 g/ml could be estimated.
