Density

Link to relevant study record(s)

Reference

Endpoint:

relative density

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

test procedure in accordance with generally accepted scientific standards and described in sufficient detail

Qualifier:

no guideline followed

Principles of method if other than guideline:

A known amount of the test substance is loaded in a well-calibrated pycnometer and the volume is filled with an efficient wetting liquid such as a silicon oil of fairly low viscosity. By subtracting the mass of the empty pycnometer from the mass of the filled pycnometer, the mass of the wetted powder content is determined. From the value of the oil density, the density of the test substance can be calculated.

Key result

Type:

relative density

Density:

1.29 g/cm³

Temp.:

23 °C

Conclusions:

Under the study conditions, the density of the test substance was assessed to be 1.29 ± 0.02 g\cm3 at 23°C.

Executive summary:

A study was conducted to determine the density of the test substance using pycnometry. The measurements were conducted at 23°C. Under the study conditions, the density of the test substance was determined to be 1.29 ± 0.02 g\cm3 (Bruggemans, 2017).

Description of key information

The relative density was determined by pyconometry (Bruggemans, 2017).
