Reference
Results of the measurement of the density of the test item
| Test No. | Temperature [°C] | Test item chamber size | Reference vessel No. | Weight in of test item [g] | Density [g/cm³]* |
| 1 | 20 | Small (25.62 cm³) | 21.35 cm³ | 20.7407 | 1.96786 |
| 2 | 20 | Small (25.62 cm³) | 21.35 cm³ | 20.1257 | 1.96993 |
*The pressurizing-expansion cycles are performed until 5 subsequent volume measurements have a relative standard deviation (RSD) >0.02%.
The mean density of the test item at 20 °C is 1.968895 g/cm³ (SD= 0.0015, RSD = 0.08 %). The relative density D(4)20 is calculated by dividing the density of the test item by the density of water at 4 °C (0.9999750 g/cm³).
The relative density is D(4)20 = 1.97
Description of key information
The relative density D(4)20 of zirconium propionate is 1.97.
Key value for chemical safety assessment
- Relative density at 20C:

Additional information
According to OECD Test Guideline 109 (1995), the relative density D(4)20 of the test item at 20 °C ± 0.01 °C (compared to water at 4 °C) is D(4)20 = 1.97.
