Conclusions:

Relative density of the test substance, Reactive Violet 1, is 1.694. Uncertainty of determination was estimated to 0.012 (Uncertainty is calculated as 0.886 times the range where 0.886 is a statistical coverage factor for two measured values.).

Executive summary:

The density of the test substance, Reactive Violet 1, was measured. The pycnometer method was used. The procedure was performed according to the Method A.3, Relative density, Council Regulation (EC) No.440/2008, Published in O.J. L 142, 2008.

Relative density of the test substance, Reactive Violet 1, is 1.694. Standard uncertainty is 0.012.

Test temperature was 20 ± 0.1°C.

Key value for chemical safety assessment
