*Conversion factor: 1 psi = 6895 Pa = 0.06895 bar
Mean density for the two test series: 1.338 cm3
Relative density (compared to water at 4 °C) : 1.34 cm3
Applicant's summary and conclusion
- Conclusions:
- In conclusion, the relative density at ambient temperature (compared to water at 4 °C) is 1.34.
- Executive summary:
A study was performed according to EU method A.3 (OECD guideline 109) to identify the relative density of the test item. The test was performed with a gas comparison pycnometer. Two individual runs were performed with three different measurements each. The relative density at ambient temperature (compared to water at 4 °C) is 1.34.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
