- Type:
- relative density
- Density:
- 1.477 other: dimensionless
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test item was determined to be 1.4773 ± 0.024 (95 % confidence interval) at 20°C.
- Executive summary:
The purpose of this study was to determine the relative density of test item using the pycnometer method according to OECD TG 109, EU Method A.3 and EPA OPPTS 830.7300. The density is calculated from the difference in weight between the full and empty pycnometer and its known volume. The relative density of the test item was determined to be 1.4773 ± 0.024 (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.
