Applicant's summary and conclusion

Conclusions:
In conclusion, the relative density at ambient temperature (compared to water at 4 °C) is 1.34.
Executive summary:

A study was performed according to EU method A.3 (OECD guideline 109) to identify the relative density of the test item. The test was performed with a gas comparison pycnometer. Two individual runs were performed with three different measurements each. The relative density at ambient temperature (compared to water at 4 °C) is 1.34.
