Applicant's summary and conclusion
- Conclusions:
- The relative density v was found to be 1.32.
- Executive summary:
The relative density of 3,3-(4,4-biphenylenedioxy)dianiline was determined relative to purified water using a pycnometer at 20 °C. Aqueous Tween 80 (0.1 % v/v) was employed as the displacement liquid. The test was conducted in accordance with EU Method A3 and OECD Method 109. Two parallel tests resulted in a mean relative density of 3,3-(4,4-biphenylenedioxy)dianiline of 1.32.
