Summary of measurements:

	Assay 1	Assay 2
Sample mass (g)	16.096	17.179
Mean sample volume (n=4) (cm^3)	10.024	10.726
Density (g/cm^3)	1.606	1.602
Mean density (g/cm^3)	1.60

The individual measurements were obtained with an accuracy of < 0.02 g/cm3. According to the guideline, the density of the test substance is given as the mean value.

The relative density (D20/4) is the ratio between the mass of a volume of a substance to be examined, determined at 20°C, and the mass of the same volume of water, determined at 4°C (ρ H2O = 1000 kg/ m³, CRC Handbook of Chemistry and Physics, 1981).

Conclusions:

The density of the test item (at 20°C) is 1.60 g/cm3. Its relative density (D20/4) is 1.60.

Executive summary:

The density of the test item was determined according to recognized guidelines (OECD Guideline 109, EU Method A.3 and EPA OPPTS 830.7300) and under GLP. The gas comparison pycnometer method was used, with helium. No deviation has been recorded during the test.

Measurements were recorded for two independant samples, and four determinations of sample volume for each, at 20°C. The average value was retained. Relative density (D20/4) was calculated considering a density of 1.000 g/cm³ for water at 4°C.

The density of the test item (at 20°C) was determined to be 1.60 g/cm³. Its relative density (D20/4) is 1.60.

Description of key information

The density of the test item (at 20°C) is 1.60 g/cm³. Its relative density (D20/4) is 1.60.

Key value for chemical safety assessment

Relative density at 20C:
