Density determination of test material (g)
Weight of test material (g) = (weight of pycnometer + test material (g)) - (weight of empty pycnometer (g))
Density of test material (g/cm³) = weight of test material (g) / calibrated volume of pycnometer (cm³)
Description of key information
Study conducted according to recognised testing guideline with GLP certification.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.926
Additional information
The density of the test material was determined under GLP conditions, in accordance with the standardised guideline OECD 109, using a pycnometer. Under the conditions of the study, the density of the test material was determined to be 0.9256 g/cm³ at 20 °C.
The study was performed in line with GLP and an accepted standardised guideline with a good level of reporting. The study was therefore assigned a reliability score of 1 and considered suitable for assessment as an accurate reflection of the substance.
The available data are considered to be complete and the result determined, relative density 0.9256 at 20 °C, was taken forward for risk assessment.
