Description of key information

The measurement of viscosity of petroleum distillates is covered by method ISO 3104. The viscosity is at maximum 0.68 mm2/s at 20°C for this substance if measured with the agreed method.According to Yaws (2003) the viscosity of 2,2,4-trimethylpentane is 0.5010, 0.4672, and 0.3868 mPa s at 20, 25, and 40°C, respectively.

Key value for chemical safety assessment
