Literature data (CRC Handbook of Chemistry and Physics 75th Edition)

d (20, w) (density of water at 20 °C) = 0.9982 g/mL

d (4, w) (density of water at 4 °C) = 0.99997 g/mL

d (20, a) (density of air at 20 °C) = 0.0012 g/mL

Conclusions:
The relative density at 20 °C of the test item was determined as D4/20 = 1.188.
Executive summary:

According to the OECD Guideline 109 (Density of Liquids and Solids) corresponding to A.3., Council Regulations EC No 440/2008 the solid sample of the test item was accurately weighed into a pycnometer and by displacement of the solvent (n-heptan), its equivalent volume was determined. Finally, the density of the sample was calculated. The relative density at 20 °C of the test item was determined as D4/20 = 1.188.

Description of key information
