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) | 76 (21.35 cm³) | 7.06 | 2.05107 |
| 2 | 20 | Small (25.62 cm³) | 76 (21.35 cm³) | 7.34 | 2.06002 |
*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 2.05555 g/cm³ (SD = 0.0063, RSD = 0.31%). The relative density D420 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 D420= 2.06
