Description of key information

Viscosity is between 0.31 and 0.52 mm2/s at 20˚C  for 2-methylbutane, based on ASTM D 445 methodology.

Key value for chemical safety assessment

Additional information

The viscosity is between 0.31 and 0.52 mm2/s at 20˚C for 2-methylbutane based on ASTM D 445 methodology. This range has been agreed by the consortium to represent the substance. This is supported by a value of 0.214 mPa s at 25°C from the CRC Handbook (Lide 2008). There is no information available on the methods used to determine the value for this endpoint. However, the CRC Handbook is considered to be a reliable, peer-reviewed handbook and suitable for use as a study for this endpoint.
