Calculations used to determine relative density:

Volume of pycnometer (mL): V = (B-A)/X

Density of test substance (g/mL): D1 = (C-A1)/V

Relative density = D1/Y

Conclusions:
The relative density of substance 1-[(2-hydroxyethyl)thio]propan-2-ol was determined to be 1.13 ± 0.01 at 20 ºC ± 0.5 ºC.
Executive summary:

A study was performed with a pycnometer device to determine the relative density of test item 1-[(2-hydroxyethyl)thio]propan-2-ol. The test was conducted in compliance with OECD Guideline 109 (Density of Liquids and Solids). Two measurements rendered a mean value of 1.13 ± 0.01 at 20 ºC ± 0.5 ºC for the relative density of 1-[(2-hydroxyethyl)thio]propan-2-ol.
