values
The density of the test substance at 20°C is
P20=2.578 g/cm3or 2578 kg/rn3.
The relative density is calculated according to the formula:
D41= PTIP4(water)
D4T relative density of the test substance
pT measured density of the test substance [kg/rn3] at temperature T [°C]
p4 (water) density of water @ 4°C 999.972 kg/rn3 (Handbook of Chemistry and Physics, 64 Ed.,1984)
The relative density of the test substance was calculated as:D04/20=2.578
Applicant's summary and conclusion
- Conclusions:
- The density of the test item was tested to be 2.578 g/cm3 at 20 °C (relative density D4/20° = 2.578).
- Executive summary:
The density and relative density of the test item were determined according to OECD guideline no. 109 [adopted on 27 July 1995] and EU test method A.3 [Council Regulation (EC) No 440/2008 of 30 May 2008] with the gas displacement pycnometer.
Density (20°C) = 2.578 g/cm3, Relative density D4/20° = 2.578
