Temp.:

20 °C

The results of duplicate determinations of relative density are shown in the table below.

Measurement	Determination
	1	2
Mass of pycnometer (g)	19.5118	19.5115
Mass of pycnometer and distilled water (g)	44.1511	44.1421
Mass of pycnometer and test material (g)	45.4333	45.3804
Temperature of test material (°C)	20.0	20.5
Density of water at 20°C (kg/m^3)	998.20	998.20
Relative density	1.05	1.05

Conclusions:

The test material is very slightly denser than water.

Executive summary:

Method: The relative density was determined using the pycnometer method and EU Method A3.

Results: The relative density D20/4 of ST 03 C 99 was determined to be 1.05 at 20 +/- 0.5°C.

Description of key information

Experimental relative density D20/4
The test material is very slightly denser than water.

Key value for chemical safety assessment

Relative density at 20C:

1.05

Additional information

An experimental study on density measurement of the test material, was conducted under GLP, and considered as fully reliable. Therefore the result is considered as key data.
