- Temp.:
- 20 °C
- Conclusions:
- In a study according to OECD guideline 109 the relative density of the test item at 20 °C ±0.01 °C (compared to water at 4 °C) was determined to be 1.19.
- Executive summary:
The relative density of the test item was determined in a study according to OECD guideline 109. In this study the relative density of the test item at 20 °C ±0.01 °C (compared to water at 4 °C) was determined to be 1.19.
Reference
Two tests with different amounts of the test item were performed to determine the relative density at a temperature of 20 °C ±0.01 °C. Table 1 compiles the results.

* The pressurizing-expansion cycles are performed until 4 subsequent volume measurements have a relative standard deviation (RSD) of ≤ 0.2 %.
The mean density of the test item at 20 °C
is 1.19 g/cm³. The relative density 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 1.19.
