Relative density (glaspycnometer)

Two calibrations with water and two tests with test item using different pycnometers were carried out at a temperature of 20°C (see Table 4.4/1).

Calibration of water and determinations of test item were within accuracy; therefore no additional measurement was needed, and the average value was given as final result.

 

 

Final results

The relative density of the test item at 20 °C (compared to water at 4 °C) according to the European Commission Regulation (EC) No. 440/2008 (A.3) and the OECD 109 guidelines, pycnometer method, was determined to be: D420=1.02 ±0.01

Conclusions:
The relative density of the test item at 20 °C (compared to water at 4 °C) according to the European Commission Regulation (EC) No. 440/2008 (A.3) and the OECD 109 guidelines, pycnometer method, was determined to be: D420 = 1.02 ± 0.01
Executive summary:

The study was performed in order to determine the density of test item according to OECD 109, resp. EU A.3 guideline, using a pycnometer.

Description of key information

The relative density of the test item at 20 °C (compared to water at 4 °C) according to the European Commission Regulation (EC) No. 440/2008 (A.3) and the OECD 109 guidelines, pycnometer method, was determined to be: D420 = 1.02 ± 0.01

Key value for chemical safety assessment

Relative density at 20C:
1.02

Additional information

A fully reliable experimental study, conducted according to OECD 109/ EU A3 guideline is available.

It is considered as a key study, and the result is retained as key data.
