Key result

Type:

relative density

Density:

1.445 other: dimensionless

Temp.:

19.9 °C

The temperature was 19.9 °C during the calibration and 19.9 °C during the measurements.
The results of the two measurements of the density for the test substance were:
1.4435 g/cm³ and 1.4460 g/cm³. The mean relative density (D²⁰₄) of the test substance was determined to be 1.4448 at 19.9 °C (mean of two samples).

The mean relative density was determined at 19.9°C as 1.4448 (individual values: 1.4435 g/cm3 and 1.4460 g/cm3).

Conclusions:

The mean relative density was determined at 19.9 °C to be 1.4448 (n=2).

Executive summary:

A study was conducted according to OECD TG 109 and Regulation (EC) No 440/2008 method A.3 to determine the relative density of the test item. The density was measured at a temperature of 19.9 °C using the gas comparison pycnometer method. Two tests with different amounts of the test item were performed to determine the relative density D₄²⁰ at a temperature of 19.9 °C. The mean density of the test item at 19.9 °C was 1.4448 g/cm³. The relative density D₄²⁰ was calculated by dividing the density of the test item by the density of water at 4 °C (1.00000 g/cm³). The relative density was determined to be D₄²⁰ = 1.4448.

Description of key information

The mean relative density was determined at 19.9 °C to be 1.4448 (n=2) (reference 4.4-1).
