Mean density: 1.11 x 103 kg/m3
Relative density: 1.11
Temperature: 20.0 ± 0.5 ºC
Discussion
Duplicate determinations were performed to ensure a reproducibility of less than ± 20 kg/m3 was obtained.
Conclusion
The density of the test item was determined to be 1.11 x 103 kg/m3 at 20.0 ± 0.5 ºC. The corresponding relative density was calculated to be 1.11.
