- Conclusions:
- The relative density of SIKA Hardener LTJ was determined to be 0.9383 ± 0.00020 at 20 °C ± 0.2 °C with respect to water at 4 °C.
- Executive summary:
A study was conducted according to OECD TG 110, Regulation (EC) No 440/2008 method A.3 and OPPTS 830.7300 to determine the relative density of SIKA Hardener LTJ. The density was determined in six independent determinations. Using the pycnometer method the density was determined to be 0.9383 ± 0.00020 g/cm3 at 20 ± 0.5 °C and the relative density 0.9383 with respect to water at 4 °C respectively. The standard deviation reflects the distinguished correlation of the individual determinations. No observations were made which cause doubt on the validity of the outcome of the study.
