Additional information

Discussion for CAS # 756-13-8:

The viscosity CAS# 756-13-8 was assessed in three studies. In the key study, CAS# 756-13-8 had a measured kinematic viscosity of 0.3922 mm2/s at 24.93°C. In the first supporting study, CAS# 756-13-8 had a measured kinematic viscosity of 0.4108 mm2/s at 25°C. In the second supporting study, CAS# 756-13-8 had a measured kinematic viscosity of 0.3273 mm2/s at 25°C. No testing protocol was cited in the three study reports. While the type of instrumentation (capillary viscometers) used for these tests is mentioned in OECD TG109, it is not known whether the instrumentation was compliant with the ISO standards specified for use with the instrument. Further it is not known whether the studies were GLP-compliant. The results of the key study are the best documented of the three reports and reflect the sponsor’s judgment of the most accurate determination of CAS# 756-13-8 viscosity. Further, the two supporting study results bracket the key study result, and the arithmetic mean of the two supporting studies (0.369 mm2/s) is reasonably close to the result of the key study.
