- Density:
- 1.042 g/cm³
- Temp.:
- 20 °C
- 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.
