Relative density - calculation:

To calculate the relative density D₄²⁰at 20 °C, the measured density of the test item ρ_TI at 20 °C is divided by the density of water ρ_W4 at 4 °C (0.9999750 g/cm³). The relative density at 20 °C D₄²⁰ is calculated according to the following equation: D₄^{20 =}ρ_{TI /}ρ_W4

D₄²⁰:   Relative density (without dimension) of the test item measured at a temperature of 20 °C compared to the density of water at 4 °C

ρ_TI:      Density of the test item measured at a temperature of 20 °C ± 0.01 °C in g/cm³

ρ_W4:    Density of water at 4 °C in g/cm³

D₄²⁰:   1.1

Conclusions:

The relative density of the test substance is 1.1.

Key value for chemical safety assessment

Relative density at 20C:
