- relative density
- Density:
- 1.115 other: dimensionless
- Temp.:
- 20 °C
- Type:
- density
- Density:
- 1.115 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test item was determined to be 1.115 ± 0.0048 at 20 °C.(95 % confidence interval).
- Executive summary:
A study was conducted according to OECD TG 109, Regulation (EC) No 92/69/EEC method A.3 and OPPTS 830.7300 to determine the relative density of the test item. The density was determined in five independent determinations. Using the air comparison pycnometer method the density was determined to be 1.115 ± 0.0048 g/cm³ at 20 ± 0.5 °C and the relative density 1.12 with respect to water at 4 °C, respectively.
Reference
The relative density of the test item is 1.115 ± 0.0048 (95 % confidence interval).
Results of the determination of density at 20 °C:
Sample Density (g/cm3) Mean (g/cm3)
#1 1.118 1.115
#2 1.115
#3 1.111
#4 1.112
#5 1.120
Description of key information
The relative density of the test item was determined to be 1.115 ± 0.0048 at 20 °C (95 % confidence interval).
Key value for chemical safety assessment
- Relative density at 20C:
- 1.115
