Materials and methods
Test guidelineopen allclose all
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7300 (Density / Relative Density / Bulk Density)
- Principles of method if other than guideline:
- The density (ρ) and relative density ( D4 20 ) of the test item were determined using a gas comparison stereopycnometer (Pycnomatic, Porotec, Frankfurt, Germany). With this method the volume of the test item is measured in helium gas (Air Products, Amsterdam, The Netherlands) in a calibrated cylinder.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- pycnometer method

Applicant's summary and conclusion
- Conclusions:
- A gas comparison stereopycnometer was used for the determination of the density and relative density of V250208.
The density of the test item at 20°C was 1.33 g/cm3 (1.33 x 10^3 kg/m3).
The relative density was 1.33.
