Conclusions:

The density of the test item Hatcol 3178 was measured, and determined to be 0.9678 ± 0.0008 g/cm3 at 20.0 ± 0.2 °C, which is the mean of two values ± standard deviation.
Correspondence of the values is very good. Therefore, the study is to be considered as valid.

Executive summary:

The study was performed to determine the density of Hatcol 3178.

Density is one of the fundamental physico-chemical properties of a chemical substance, and is calculated using the difference in weights between a full and empty pycnometer, and its known volume.

 

Using the pycnometer method, a density of

0.9678 ± 0.0008 g/cm³at 20.0 ± 0.2 °C

was measured. This value is the mean of two independent determinations ± standard deviation.

Standard deviation was 0.0008 g/cm³, showing very good correlation of the two determinations.
