No data if single or multiple determinations.

Conclusions:
The substance is much less dense than water.
Executive summary:

The density of the test substance was measured with a procedure similar to the OECD guideline, oscillating densitimeter method.

After calibration with air and water, the sample was measured at 20, 25, 30 and 40°C.

The density of exo-THDCPD (JP-10) was determined as 0.9356 g.cm-3 at 20°C and 0.9312 g.cm-3 at 25°C.

The density of THDCPD was measured as 0.9314 g/cm3 at 25°C.

Description of key information

The density of THDCPD was determined as 0.9356 g.cm-3 at 20°C and 0.9314 g.cm-3 at 25°C.

The relative density (D20/4) was calculated as 0.9356.

Key value for chemical safety assessment

Relative density at 20C:
0.936

Additional information

Two reliable publications were identified, providing consistent values. However, in Xing 2009 the density was measured only at 25°C, while Wei 2010 provides values at four temperatures, including 20°C which is the prefered reference temperature for relative density (D20/4). Therefore it is considered as key data.
