Applicant's summary and conclusion

Conclusions:
In this peer-reviewed database, sodium fluoride is reported to have a density on average around 2.7583g/mL at 20 °C (+/- 2 °C) at atmospheric pressure for three references reviewed and five values reported. The densities range from 2.712 to 2.809 g/mL at 20 °C (+/- 2 °C) at atmospheric pressure.
Considering a water density of 0.999975 g/mL at 4 °C, a mean value of the relative density of sodium fluoride was calculated. It results to a relative density around 2.76 at 20 °C (+/- 2 °C) at atmospheric pressure.
Executive summary:

In this peer-reviewed database, sodium fluoride is reported to have a density on average around 2.7583g/mL at 20 °C (+/- 2 °C) at atmospheric pressure for three references reviewed and five values reported. The densities range from 2.712 to 2.809 g/mL at 20 °C (+/- 2 °C) at atmospheric pressure.

Considering a water density of 0.999975 g/mL at 4 °C, a mean value of the relative density of sodium fluoride was calculated. It results to a relative density around 2.76 at 20 °C (+/- 2 °C) at atmospheric pressure.

According to the ECHA Guidance on information requirements and chemical safety assessment, Chapter R.7a: Endpoint specific guidance, the Gmelin database, related to the Beilstein database should be considered as a peer-reviewed database. Hence, these values are considered as reliable with restrictions and equivalent to data from Handbook.
