Any other information on results incl. tables
The density value at 20°C was calculated according to the formula:
Density (g/mL) = 0.9982 x S x (W6 - W5) / (W4 - W3) - (W7 - W6)
The specific gravity of the test item at 20°C is determined by the ratio between the mass of a volume of the substance and the mass of the same volume of water: it was obtained according to the formula:
Specific Gravity = density (g/mL) / 0.9982 (g/mL)
Since the density of distilled water at 4°C is 1.0000 g/mL, the relative density, (D20 4) defined as the ratio between the mass of a volume of the substance at 20°C and the mass of the same volume of water at 4°C, is the dimensionless numeric value of the density.
Applicant's summary and conclusion
- Conclusions:
- From the experimental data obtained according to the guideline A.3 in Council Regulation (EC) No 440/2008 part A, CIPAC method MT 3.2 and OECD Test No 109, it can be concluded that the density of the Soybean (Glycine max) dry purified extract sample is 1.3254 g/mL at 20°C; the specific gravity is 1.3278 at 20°C, and the relative density (D20 4) is 1.3254.
