The relative density of the sample at 15 °C, compared with water at 15 °C, was calculated according to the following formula:

 

ρtwt = ρt / ρtw= 0.9354 / 0.9991 = 0.9362

 

ρtwt: relative density of the sample at temperature t (15 °C), compared with water at temperature tw (15 °C)

ρt: measured density of the sample at temperature t (15 °C)

ρtw: density of water at temperature tw (15 °C)

The relative density of the sample at 15 °C, compared with water at 15 °C, was calculated according to the following formula:

 

ρtwt = ρt / ρtw = 0.9287 / 0.9991 = 0.9295

 

ρtwt: relative density of the sample at temperature t (15 °C), compared with water at temperature tw (15 °C)

ρt: measured density of the sample at temperature t (15 °C)

ρtw: density of water at temperature tw (15 °C)

Description of key information

Relative density range: 0.9295 to 0.9362 at 15 °C (ASTM D7042, oscillating densitimeter)

Relative density calculated in comparison with water at 15 °C.

Key value for chemical safety assessment

Additional information

The density changes with the composition of the substance.

Experimental data are available for two compositions (named grade one and grade two). The following relative densities were determined for them:

Grade one: 0.9362

Grade two: 0.9252
