Expiry date: 30 October 2018
Date received: 12 November 2015 - GLP compliance:
- yes (incl. QA statement)
- Type of method:
- air comparison pycnometer (for solids)
- Specific details on test material used for the study:
- dentity: RM1006114
Appearance: White creamy solid (at 20°C)
Storage conditions: Room temperature (15 to 25°C)
Batch number: RL 686/15
Purity: 100%
Expiry date: 30 October 2018
Date received: 12 November 2015 - Key result
- Type:
- bulk density
- Density:
- ca. 1.02 other: N/A
- Temp.:
- 20 °C
- Conclusions:
- The substance relative density was evaluated in accordance with OECD Guidelines 109 and EU Method A.3 via GLP certified laboratory using the pyknometer method. The relative density was determined to be 1.02 after measurements at 20 °C.
- Executive summary:
The substance relative density was evaluated in accordance with OECD Guidelines 109 and EU Method A.3 via GLP certified laboratory using the pyknometer method.
A clean, dry pyknometer was accurately weighed , test item (3 g) was added and the pyknometer was re-weighed . The test item was covered with displacement liquid ( 0.1% v/v aqueous Tween 80). After vigorous shaking of the stoppered pyknometer, to suspend the test item, air bubbles were removed by ultrasonication and the pyknometer was weighed as before. The
pyknometer was filled with displacement liquid, stoppered and weighed. The relative density was then calculated from these results.
The relative density was determined to be 1.02 after measurements at 20 °C.
