- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test item, Dilithium salicylate, at 20 °C ± 0.01 °C (compared to water at 4 °C) is D420 = 1.432.
- Executive summary:
This study is GLP compliant and follows OECD guideline 109 and EU method A3. Therefore, it is given a reliability rating of 1 (reliable without restrictions).
According to OECD Test Guideline 109 (2012) and Regulation EC No. 440/2008 Part A Method A.3., the relative density D420 of the test item, Dilithium salicylate, at 20 °C ± 0.01 °C (compared to water at 4 °C) is D420 = 1.432.
Reference
Two tests with different amounts of the test item were performed to determine the relative density D420at a temperature of 20 °C ±0.01 °C. The following table compiles the results.

* The pressurizing-expansion cycles are performed until 5 subsequent volume measurements have a relative standard deviation (RSD) of ≤ 0.2 %.
The mean density of the test item at 20 °C is 1.431556 g/cm³. The relative density D420is 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=1.432.
