-163.3 °C = 5.768 Cohen and Olie; Z. Physic. Chem., 71, 385 (1910)

Conclusions:
The specific gravity of tin was reported as 7.184 at 226 °C and 7.30 at 21 °C for white tin and as 5.75 and 5.768 for grey tin.
Executive summary:

The specific gravity of tin was noted as being between 7.184 at 226 °C and 7.30 at 21 °C for white tin and 5.75 and 5.768 for grey tin.

Conclusions:
The specific gravity for beta tin at 15 °C was 7.29 g/cm³, 7.281 g/cm³ at 25 °C and for grey tin 5.77 g/cm³ and 5.765 g/cm³ respectively.
Executive summary:

The specific gravity of tin was noted as being between 7.29 g/cm³ at 15 °C and 7.281 g/cm³ at 25 °C for beta tin and 5.77 g/cm³ and 5.765 g/cm³ for grey tin.

Description of key information

A number of articles in the public domain, published papers and Safety Data Sheets record the melting point of tin as ranging from 7.26-7.31 g/cm³.

Key value for chemical safety assessment

Relative density at 20C:
7.31

Additional information

The relative density of tin recorded in the articles in the public domain for which legitimate access is available is 7.26 -7.31g/cm³ which covers the range of data available and so these values are considered acceptable. A value of 7.31g/cm³ has been chosen on the basis that this result is most commonly reported
