Remarks:
Also according to GLP
Qualifier:
according to guideline
Guideline:
EU Method A.3 (Relative Density)
Version / remarks:
1984
Qualifier:
according to guideline
Guideline:
other: ISO R1183
GLP compliance:
yes
Type of method:
pycnometer method
Type:
relative density
Density:
1.394 other: no unit
Temp.:
20 °C

Calibration factors for the pycnometer used in tests 1 and 2 were calculated as 0.99707 and 1.0006 respectively.

The test substance density was determined as 1393.9 kg/m³ (mean of 1391.4 and 1396.3 kg/m³ for test 1 and 2 respectively).

Conclusions:
The density of the test material at 20ºC was 1393.9 kg/m³ and the relative density was 1.3939.
Executive summary:

The density of the test material has been determined according to EC A.3 method and OECD test guideline 109 in compliance with GLP. A pycnometer was used for the determination of the density and relative density. The density of the test substance at 20ºC was 1393.9 kg/m³ and the relative density was 1.3939.

Description of key information

Relative density at 20 °C: 1.3939

Key value for chemical safety assessment

Relative density at 20C:
1.39

Additional information

The relative density of the substance was determined according to EEC Method A.3 (1984). The pycnometer method as described in ISO Recommendation R1183 was applied.
