Executive summary:

The specific gravity of the test substance, determined by procedures given in ASTM D4052, is 0.9049 at 15.6 deg. C

Conversion to density (density of water at 15.6°C = 0.999012) = 904 kg/m3

Description of key information

Relative density of the analogue test item was determined to be 0.940 at 20.0 °C (OECD 109 and EC Method A.3).

Key value for chemical safety assessment

Relative density at 20C:
0.94

Additional information

Relative density of the analogue test item, determined according to EC Method A.3 and OECD 109 (pycnometer method), was found to be 0.940 at 20.0 °C.
