Equation: ETA.L = exp(A+B/(t+C))
Units: [t] = °C [ETA.L] = mPa*s
Error : 0.15 % (average deviation)
Parameters: A = -1.65258 B = 628.309 C = 119.224
Measuring range: 21.8 to 130.8 °C
The viscosity at 20 °C and 40 °C was obtained by intrapolation/extrapolation from the measured viscosity curve.
Applicant's summary and conclusion
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
