Conclusions:
Using the gas comparison pycnometer method the density of Urea 4 was determined to be 1.042 g/cm³ at 20 °C.
Executive summary:

The relative density of Urea 4 was determined according to EU method A.3, OECD Guideline 109, and EPA OPPTS 830.7300 guideline. The density of Urea 4 was determined to be 1.042 g/cm³ at 20 °C using a gas comparison pycnometer. The determination of the relative density of Urea 4 was performed by five-fold measurements of two independent test substance samples.

Description of key information

Using the gas comparison pycnometer method the density of Urea 4 was determined to be 1.042 g/cm³ at 20 °C.

Key value for chemical safety assessment

Relative density at 20C:
