- 20 °C
- Conclusions:
- The relative density (D204) of the test item was found to be 1.41.
- Executive summary:
The relative density of the test item was determined according to Regulation (EC) No 440/2008 Part A. Method A.3 and OECD Test Guideline 109. Using the pycnometer method a relative density 1.41 was measured. This value is the mean of two independent determinations.
