JUSTIFICATION FOR DATA WAIVING
Statement as presented in the study report: "The test item is a very viscous liquid. Due to its high viscosity, introducing the test item into the viscometer is technically not possible. The test item was therefore visually compared to a reference oil with known viscosity (Viscosity & Density Reference Standard type N18000; kinematic viscosity of 106285 mm2/s at 20°C; Paragon Scientific Ltd, Prenton, United Kingdom).

The test item was visually more viscous than the reference oil and has therefore a kinematic viscosity which is higher than the reference oil.

The test was performed at 19.9°C.

The kinematic viscosity of T106D is > 106285 mm2/s at 20°C."

Applicant's summary and conclusion

Conclusions:
The relative density D20/4 of the substance was determined to be 1.19.
Executive summary:

The relative density of the substance was determined in a GLP study according to EC A.3, OECD 109 and OPPTS 830.7300. A gas comparison pycnometer was used with Helium as the gas.

The relative density D20/4 was determined in duplicate obtaining a mean value of 1.19.
