Applicant's summary and conclusion
- Conclusions:
- The test substance is denser than water. The mean relative density of the test item, using the gas comparison method with the stereopycnometer, was 1.234 ± 0.030 at 18.6 °C ± 0.3 °C
- Executive summary:
The density of the test substance was measured under GLP according to OECD 109 / EU A3 guideline, using gas comparison pycnometer method. After calibration, two independent samples were measured in triplicate.
The mean relative density of the test item, using the gas comparison method with the stereopycnometer, was 1.234 ± 0.030 at 18.6 °C ± 0.3 °C
