Temp.:
20 °C
Conclusions:
Relative density of the test substance, Reactive Blue 234, is 1.140. Uncertainty of determination was estimated to 0.018 (*).(*) 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 Blue 234, 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 Blue 234, is 1.140.

Standard uncertainty is 0.018*.

* Standard uncertainty is equal to one standard deviation.

Test temperature was 20 ± 0.1°C.
