Using the helium pycnometer method, the density of the barium sulfonate test substance was obtained at room temperature (approximately 22°C). The sample masses used ranged from 1.2 to 2.3 grams. The overall mean density result for the three samples was 1.0578 ± 0.0092 g/cm3 (1057.8 ± 9.2 kg/m3). The results of the density determinations are presented in Table below.

Relative density can be calculated. Reference density is water density at 4 °C ( 0.999975 g/cm3):

D22/4 = ((1.0578 g/cm3) / (0.999975 g/cm3)) = 1.0578

Conclusions:
The overall mean density result for the three samples was 1.0578 ± 0.0092 g/cm3 (1057.8 ± 9.2 kg/m3) at 22 °C. The relative density D22/4 can be calculated as 1.0578.
Executive summary:

This study was performed in accordance with GLP, OECD guideline 109 and US EPA OPPTS 830.7300.

The overall mean density result for the three barium sulfonate test samples was 1.0578 ± 0.0092 g/cm3 (1057.8 ± 9.2 kg/m3) at 22 °C. The relative density D22/4 can be calculated as 1.0578.

Description of key information

This study was performed in accordance with GLP, OECD guideline 109 and US EPA OPPTS 830.7300.

The overall mean density result for the three samples was 1.0578 ± 0.0092 g/cm3 (1057.8 ± 9.2 kg/m3) at 22 °C. The relative density D22/4 can be calculated as 1.0578.

Key value for chemical safety assessment

Relative density at 20C:
1.058

Additional information

Relative density shown above is at a temperature of 22 °C. The difference of 2 °C should not show any relevant effects on the relative density.
