Table 1: Results

Measurement	Density 20°C [g/cm^3]	Relative density D20/4*
Test 1	1.17318	1.17322
Test 2	1.17321	1.17325
Mean value	1.173	1.173

*The relative density D_20/4is the ratio between the measured density of the test substance at 20°C and the density of water at 4°C (= 0.9999 7 g/cm³). The relative density has no dimension.

 

Check measurement: Density of degassed deionized water at 20°C: 0.99820 g/cm³

Reference value: 0.99820 ± 0.00005 (20°C)

Conclusions:

A relative density value of 1.173 at 20°C was determined for the substance using a relevant test method and in compliance with a known quality system. The result is considered to be reliable.

Description of key information

Relative density: 1.173 at 20°C (EU Method A.3)

Key value for chemical safety assessment

Relative density at 20C:

1.173

Additional information

A relative density value of 1.173 at 20°C was determined for the substance using an oscillating densitimeter in accordance with EU Test Method A.3 and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable and is selected as key study.

In available secondary sources to which reliability could not be assigned, density values of 1.176 g/cm³ at 20°C and 1.17 g/cm³ at 25°C were reported for the substance.
