Description of key information

The densitiy of norbornene as a mean value of two measurements at 20.0 +/-0.5°C was determined as 0,8706 +/- 0.0023 g/cm³.

Key value for chemical safety assessment

Relative density at 20C:

Additional information

the density was determined with the pycnometer method (OECD 109). At 20,0 +/-0,5°C a value of 0,8706 g/cm³ was determined as average of 2 measurements with a standard deviation of 0,0023 g/cm³ and an error of determination of 0,0001 for each measurement value.

in a second study the relative density of molten norbornene at temperatures ranging from 50°C (0.8449) to 90°C (0.8126) was measured.

Because the given values
