Applicant's summary and conclusion
- Conclusions:
- The kinematic viscosity of Novec 7700 is 1.73 mm2/s at 40.0 °C.
- Executive summary:
The kinematic viscosity of Novec 7700 is 1.73 mm2/s at 40.0 °C. The study was well-documented and a method equivalent to OECD 114 was used but the study was not conducted in accord with GLP guidelines; therefore the result is considered reliable with restrictions.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
