Additional information
The viscosity is required at 40 °C for classification and labelling, but is only available from Meng (2008) at elevated pressure (ca. 4 atm) due to the design of the experimental apparatus. However, as the data-set is pressure dependant it can be shown that the effect on the viscosity at this pressure is negligible, and within the experimental error. As a result, the data is considered to be of sufficient accuracy for the purposes of classification and labelling, and risk assessment. The study is very well documented. The study quantified systematic errors and compared the results with previous workers. As a result, testing does not appear scientifically necessary based on the use of existing data and, given the above points, the criteria in Regulation (EC) No. 1907/2006, Annex XI, 1.1.1 are considered to be met.
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.
