Applicant's summary and conclusion
- Conclusions:
- The density of the test item has been determined to be 1210 kg/m3 at 21.0 ± 0.5 °C.
- Executive summary:
Method
The determination was carried out using a gas comparison pycnometer procedure designed to be compatible with Method A3 Relative Density of Commission Regulation (EC) No 440/2008 of 30 May 2008, Method 109 of the OECD Guidelines for Testing of Chemicals, 27 July 1995, and Method 830.7300 of the OPPTS Guidelines, June 2012.
Result
The density of the test item has been determined to be1.21 x 103 kg/m3 at 21.0 ± 0.5 °C.
