Table 1: Density result

Measurement	Density 20°C [g/cm^3]	Relative density D20/4^*
Test 1	1.56360	1.56365
Test 2	1.56358	1.56363
Mean value	1.564	1.564

*The relative density D_20/4 is the ratio between the measured density of the test substance at 20°C and the density of water at 4°C (= 0.99997 g/cm³). The relative density has no dimension.

Conclusions:

A relative density value of 1.564 at 20°C has been 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: 1.564 at 20°C (EU Method A.9)

Key value for chemical safety assessment

Relative density at 20C:

1.564

Additional information

A measured relative density value of 1.564 at 20°C was determined for the substance using an oscillating densitimeter in accordance with EU Test Method A.9 and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable and is selected as key study. The key value is supported by a predicted density of 1.5 g/cm³ at 20°C which was determined for the substance using a validated QSAR estimation method. Although the predicted result is outside the range of the model of 0.8 - 1.4 g/cm³, the result is considered sufficient to support the key study.
