The mean relative density was 1.064 with a standard deviation of 0.0012. The test temperature was 20 °C and the density of water at this temperature was 0.9982 g/cm³.

Conclusions:

The relative density (D420) of Incozol LV was determined to be 1.064 at 20 °C with a standard deviation of 0.0012.

Executive summary:

A study was conducted according to OECD TG 109 and Directive 92/69/EEC to determine the relative density of the test item using the pycnometer method. The density was determined from weight and volume measurements of the liquid substance. Calibration of the volume of the pycnometer bottle was achieved determining the difference in weight between the dry (empty) bottle in air and the bottle full of a liquid of known density (water). From this weight the volume of the bottle was calculated using the density of the water at the test temperature. The density of the liquid test substance was then deduced from the mass and volume measurements. The relative density (D420) of Incozol LV was determined to be 1.064 at 20 °C with a standard deviation of 0.0012.
