Conclusions:
The density of SIKA Hardener MTJ was determined to be 0.9952 ± 0.0001 at 20 °C ± 0.2 °C and the relative density was determined to be 0.9952, respectively.
Executive summary:

A study was conducted according to OECD TG 109 and Regulation (EC) No 440/2008 method A.3 to determine the relative density of SIKA Hardener MTJ. The density was determined in two independent determinations. Using the pycnometer method the density was determined to be 0.9952 ± 0.0001 g/cm³ at 20 ± 0.2 °C. The relative density of SIKA Hardener MTJ was determined to be 0.9952, respectively. The standard deviation reflects the distinguished correlation of the two determinations. Thus, the study was regarded to valid.
