Description of key information

The viscosity of octane is 0.801 mm2/s a at 20 °C.

Key value for chemical safety assessment

Additional information

The measurement of viscosity of petroleum distillates is covered by method ISO 3104. The viscosity is at minimum 0.61 mm2/s at 20 °C for this substance if measured with the agreed method. A test conducted by Halterman Products (2010) demonstrates that measured values fall above this borderline value with 0.801 mm2/s at 20 °C. Literature data suggest a dynamic viscosity of 0.508 mPa s (Lide 2005).
