Any other information on results incl. tables

The temperature was 20.2 °C during the calibration and 20.0 °C respectively 19.9 °C during the measurements.

The results of the two measurements of the density for the test substance were:
1.2614 g/cm3and 1.2626 g/cm3.The mean relative density of "Grewe-diamin" was determined to be 1.2620 at 20 °C (two samples).

Applicant's summary and conclusion

Conclusions:
The mean relative density of the test substance was determined to be 1.2620 at 20 °C.
Executive summary:

The relative density of "Grewe-diamin" was determined by a gas comparison pycnometer method using a multi-pycnometer.

The temperature was 20.2 °C during the calibration and 20.0 °C respectively 19.9 °C during the measurements.The results of the two measurements of the density for the test substance were: 1.2614 g/cm3and 1.2626 g/cm3.

The mean relative density of "Grewe-diamin" was determined to be 1.2620 at 20 °C (two samples).
