Relative density D20/4:

Experiment 1: 1.447

Experiment 2: 1.440

Mean: 1.44

Conclusions:
The relative density D20/4 of the substance was determined to be 1.44
Executive summary:

The relative density of the solid substance was determined at 20°C using a gas comparison pycnometer in a GLP study according to EC A.3, OECD 109 and OPPTS 830.7300. The relative density D20/4 was determined in duplicate obtaining a mean value of 1.44.

Description of key information

The relative density D20/4 of the substance was determined to be 1.44 using a gas comparison pycnometer (GLP study according to EC A.3, OECD 109 and OPPTS 830.7300).

Key value for chemical safety assessment

Relative density at 20C:
