- relative density
- Density:
- 1.507
- Temp.:
- 19.9 °C
- Conclusions:
- The relative density at 20 °C (compared to water at 4 °C) of the test item was found to be 1.5068.
- 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 air comparison pycnometer method. The relative density at 20 °C (compared to water at 4 °C) of the test item was found to be 1.5068. This value is the mean of two experiments with five replicates each.
