The density (in g/cm³) at 20 °C of the substance was published, d = 1.0024 g/cm³.

 

The relative density compared to water at 4 °C was then calculated according to “EU Test guideline A.3 for relative density Regulation (EC) No 440/2008” and “ECHA Guidance on Information Requirements and Chemical Safety Assessment, Chapter R.7a: Endpoint specific guidance”.

The density of water at 4 °C (at which temperature, water has its maximum density) is 999.975 kg/m³ (0.999975 g/cm³).

The relative density of the test substance is obtained as follows:

D₄²⁰ = density of test item at 20 °C / density of water at 4 °C = 1.0024 g/cm³ / 0.999975 g/cm³ = 1.0024
