Description of key information

The viscosity of isoheptane is 0.5 - 0.8 mm2/s at 20 °C.

Key value for chemical safety assessment

Additional information

The measurement of viscosity of petroleum distillates is covered by method ASTM D445 or DIN 51562. A range of 0.5 to 0.8 mm2/s at 20 °C covers all possible grades within this substance description if measured with the agreed method. A test conducted by DHC (2010) according to DIN 51562 demonstrates that measured values fall within this borderline value with 0.792 mm2/s at 20 °C.
