- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Version / remarks:
- OJ No. L383A, 29.12.92
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- pycnometer method
- Specific details on test material used for the study:
- Batch No.: 960509
Purity: 92.3% - Type:
- relative density
- Density:
- 1.44 other: dimensionless
- Temp.:
- 20 °C
- Conclusions:
- The relative density is 1.44.
- Executive summary:
The relative density was determined using the pycnometer method as described in OECD 109 and ECA3.
The relative density was determined to be 1.44.
- Endpoint:
- tap density
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Principles of method if other than guideline:
- The bulk and tap density of the powder was measured using a measuring cylinder. A weighed amount of the powder was placed in a measuring cylinder and the volume was recorded (bulk density). The cylinder was tapped to settle the powder until no further volume reduction occurred (tap density). The volume of the powder was recorded. It is assumed that the particle size of the powder is less than 1mm and any lumps are easily broken.
- GLP compliance:
- no
- Type of method:
- pour and tap (for solids)
- Type:
- bulk density
- Density:
- 0.81 g/cm³
- Temp.:
- 22 °C
- Key result
- Type:
- tap density
- Density:
- 1.02 g/cm³
- Temp.:
- 22 °C
- Conclusions:
- Bulk and tap density was determined to be 0.81 and 1.02 g/cm3, respectively.
- Executive summary:
The bulk and tap density of the powder was measured using a measuring cylinder. Bulk and tap density was determined to be 0.81 and 1.02 g/cm3, respectively.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
