Additional information

The test covers the determination of the dynamic viscosity of alpha-methylcinnamaldehyde (Cyprinal) using a U-tube capillary tube in a temperature controlled water bath. The test was carried out in accordance with OECD method 114, adopted 12 May 1981 Section a, flow of liquid under gravity through a capillary, (capillary viscometer or flow cup) with the procedure from IS03104:1994(E) applied. There were no deviations from the stated method.
