- relative density
- Density:
- 1.131
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test item was determined to be 1.1313 ± 0.01182 (with 95 % confidence interval) at 20 °C.
- Executive summary:
A study was conducted according to OECD TG 109, Regulation (EC) No 440/2008 method A.3 and OPPTS 830.7300 in order to determine the relative density of the test item by using the pycnometer method. The density tester determined automatically the volume of sample and the density was calculated. Five parallel tests were performed at 20 ± 0.5 °C. The relative density of the test item was determined to be 1.1313 ± 0.01182 (with 95 % confidence interval) at 20 °C.
Reference
The density of the test item was determined from five replicates at 20 °C. The results are given in Table 1.
