Discussion

Duplicate determinations were performed to ensure a reproducibility of less than ± 20 kg/m3was obtained.

The mass density of a substance varies with temperature and pressure and this variance is typically negligible for solids. Increasing the temperature of a substance may decrease its density by increasing the volume of that substance. Typical thermal expansion coefficients of solids are in the order of 10-5°C-1, and the volumetric expansion of stainless steel (used as calibration spheres) at 20 °C is approximately 5.2 x 10-5°C-1. Therefore, a change in temperature of several degrees will have no significant effect on the volume and hence the density of a solid substance.

Therefore, it was considered that the difference in temperature between 20.0 °C and normal laboratory conditions did not have a significant effect on the determined density, and therefore the calculated relative density.

Conclusions:
The density of the test item was determined to be 1.15 x 103 kg/m3 at 19.0 ± 1.0 ºC. The corresponding relative density was calculated to be 1.15.
Executive summary:

The general physico-chemical properties of 4,4'-Isopropylidenediphenol, oligomeric reaction products with 1-chloro-2,3-epoxypropane, reaction products with diethylenetriamine have been determined. 

Density. 1.15x 103kg/m3at19.0 ± 1.0ºC, the corresponding relative density was calculated to be 1.15, using the gas pycnometer method, designed to be compatible with Method A.3 Relative Density of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 109 of the OECD Guidelines for Testing of Chemicals, 02 October 2012.
