- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline

- Density:
- 1.228 other: dimensionless
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the tested material was determned to be 1.228 at 20ºC.
- Executive summary:
Determination of density was carried out in accordance with OECD 109 Guideline and EU method A.3, with GLP. The density determination of the tested material was performed using the Gay-Lussac pycnometer. Two measurements were performed and considered enough as the difference between results was less than 0.03 g/ml. The average measured absolute density of the tested material at 20°C was 1.228 g/mL. The average calculated relative density of the tested material at 20°C was 1.228.

Note: As the difference between results was less than 0.03 g/ml; hence two trials were enough.
