- Executive summary:
The test is carried out using a rotational viscometer and the value is measured at 20°C and 40°C. The rotational viscometer works with a spindle (cylinder or disk) submerged in the sample to be tested, measuring the force applied to overcome the resistance against rotation or flow. A spring is connected between the spindle and the motor shaft which is rotating at a certain speed. The deviation angle of the spindle with respect to measuring springs is measured electronically obtaining a torque value. The torque value measured with the viscometer is based on the rotating speed and the geometry of the spindle; the result is a direct reading of the viscosity value in cP (centipoise).
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.
