Results of the density measurements

Sample number Sample weight (g) Sample volume (cm3) Density (g/cm3)
1 1.8852 1.3644 1.3817
2 1.6719 1.1931 1.4013
3 1.9991 1.4177 1.4101
4 1.9204 1.375 1.3967
5 2.12 1.5084 1.4054
Mean: 1.399
Confidence interval (95 %): 0.01351
RSD %: 0.8

The measured density of test item was 1399.0 ± 13.51 kg/m3.

Conclusions:
Relative density: 1.40 at 20 °C
Executive summary:

The relative density was determined inn accordance to the OECD guideline 109. The test item was filled into the empty, clean sample cell and the weight was measured. The volume of sample was determined automatically by the density tester. The density was calculated. Five parallel tests were performed and the test was conducted at a temperature of 20 ± 0.5 °C.

The measured density of test item was 1399.0 ± 13.51 kg/m3; the relative density was determined to be 1.40.

Conclusion

Relative density: 1.40 at 20 °C

Description of key information
