Determining the density of the test item.

 Run Number
 Mass of empty pycnometer (g)  23.41 24.07 
 Mass of test item & pycnometer (g)  46.88 47.72
 Mass of test item added to empty pycnometer (g)  23.47 23.65
 Mass of test item, pycnometer & immersion liquid  46.88 47.72 
 Calculated density of test item (g.cm3)  0.935 0.934
 Density of test item (kg.m-3)  935 934 
 Mean results (kg.m-3)     935
Conclusions:
The Relative density was determined to be 0.935 at 20°C and the density to be 935 kg.m-3 at 20°C.
Executive summary:

The test is conducted to determine the relative density of a solid or liquid substance using the pycnometer method.

The test is conducted in accordance with the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A.3 and OECD Test Guideline 109.

The density was determined to be as following :

Relative density: (D204) 0.935

Test Item density: 935 kg.m-3@ 20°C

Description of key information

The Relative density was determined to be  0.935 at 20°C and the density to be  935kg.m-3 at 20°C.

Key value for chemical safety assessment

Relative density at 20C:
0.935
