Specific details on test material used for the study:

Identity: FAT 40824/A
Batch: Red ROE 805 BOP 04/05
Appearance: dark red powder
Purity: Organic part (Na-salt): approx. 82 %; Main component 1: approx. 36.2 %; Main component 2: approx. 27.5 %; Oligomers: 10 %
Expiration date: 01 October 2010
Storage: At room temperature at about 20 °C in a desiccator (hygroscopic)

Type:

relative density

Density:

1.67 g/cm³

Temp.:

19.5 °C

The test was performed at a temperature of 19.5 °C. The calibration procedure was performed in triplicate. The determination of the relative density of the test item was performed with two independent test item samples each at least measured in triplicate. The density of FAT 40824/A was determined to be 1.67 g/cm³ (= 1.67 * 10³ kg/m³) at 19.5 °C using a gas comparison pycnometer.

Conclusions:

The density of FAT 40824/A was determined to be 1.67 g/cm3 at 19.5 °C using a gas comparison pycnometer.

Executive summary:

In a GLP-compliant study, the determination of the relative density of the test item was performed in accordance with the EU method A.3 and the OECD Guideline 109 using a gas comparison pycnometer.The test was performed at a temperature of 19.5 °C. The determination of the relative density of the test item was performed with two independent test item samples each at least measured in triplicate. Based on the study results, the density of FAT 40824/A was determined to be 1.67 g/cm³ (= 1.67 * 10³ kg/m³) at 19.5 °C using a gas comparison pycnometer.

Description of key information
