Absolute density also determined by oscillating densitometry using an Anton Paar DSA5000M calibrated with ethyl acetate. Trials were performed in duplicate. Density at 20 °C was 1.8004 g/cm3 in each trial. Dynamic viscosity of 8.46 Pa.s slightly exceeds maximum applicability limit of 5 Pa.s in method guidelines, but is in agreement with the relative density determined by pycnometry. Density at 40 °C was 1.7593 g/cm3 by the oscillating densitometric method.
Applicant's summary and conclusion
- Conclusions:
- The relative density of TFEE-5 at 20 °C (D 20,4) is 1.80
- Executive summary:
The relative density of TFEE-5 was measured by pycnometry and oscillating densitometry at 20 °C according to OECD109 and EC No. 440/2008, A.4. The relative density of TFEE-5 at 20 °C (D 20,4) is 1.80 by both methods.
The study was performed according to internationally accepted test guidelines but was not done under GLP or other QA criteria. This study is classified as reliable with restrictions.
