Any other information on results incl. tables
The calibration showed that the cell volume was within acceptable limits. The test temperature was 20 °C. The sample cell volume was 15,9698 cm3. The expansion cell volume was 74,5505 cm3. The weight of test substance measured was 2,9432 g. The mean density was 1,3791 g/cm3(1379.1 kg/m3), with a standard deviation (σn-1) of 0,0011.
The relative density compared to the density of water at 4°C (1g/cm3) was then calculated and the mean relative density was 1,3791.
Applicant's summary and conclusion
- Conclusions:
- The relative density of Oxypyrionacetate was determined as 1,3791.
