Calculation of the relative density

D4/20 = 1.717 g/cm³ / 0.99997 g/cm³ = 1.717

Conclusions:
The relative density of test substance was determined to be 1.717.
Executive summary:

The determination of the relative density of the test substance was performed under GLP in accordance with the EEC Directive 92/69 and Council Regulation (EC) No. 440/2008, Part A, Methods for the determination of physico-chemical properties, A.3 ”Relative density” and the OECD Guideline for Testing of Chemicals, No. 109, ”Density of Liquids and Solids”, using a gas comparison pycnometer. The test was performed at a temperature of 19.7 °C. The calibration procedure was performed in triplicate. Based on the findings of the study, the density of the test substance was determined to be 1.717 g/cm³ (= 1.717 • 10³ kg/m³) at 19.7 °C using a gas comparison pycnometer.

Description of key information

The relative density of FAT 40851/A was determined to be D4 /20 = 1.717.

Key value for chemical safety assessment

Relative density at 20C:
1.717
