Relative Density

Two tests with different amounts of the test item were performed to determine the relative density D₄²⁰ at a temperature of 20 °C ± 0.01 °C. Table 1 compiles the results.

Table 1:    Results of the measurement of the density of the test item

Test No.	Temperature [°C]	Amount of test item [g]	Average sample volume [cm³]	Density [g/cm³]*
1	20	12.05	7.01690	1.71728
2	20	12.35	7.16020	1.72481

* 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 1.721045 g/cm³. 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=1.7211.

Applicant's summary and conclusion

Conclusions:

According to OECD Test Guidelines 109 (2012), Regulation EC No. 440/2008 Method A.3. and EPA OCSPP Test Guideline 830.7300 (2002), the relative density D420 of the test item Leuco Sulphur Brown 46 at 20 °C ± 0.01 °C (compared to water at 4 °C) is 1.7211.
