- Purity test date: July 2017

Dynamic viscosity of test material:

Pre-test for viscosity
At first the test item was inspected for the viscosity. It was checked if the test item was flowable and if it was possible to inject the test item with a one way syringe.
Result: The test item was flowable and it was possible to inject the test item with a one way sy-ringe

Density:

>= 1.615 - <= 1.615 g/cm³

Temp.:

20 °C

Conclusions:

Using the pycnometer method, a density of 1.6154 ± 0.0001 g/cm3 at 20 ± 0.4 °C was measured.

Executive summary:

This study according to OECD 109, using the pycnometer method was performed in order to determine the density of the test item .The density is one of the fundamental physico-chemical properties of a chemical substance. The density is calculated from the difference in weight between a full and empty pycnometer and its known volume.

The density of the test item was calculated as 1.6154 ± 0.0001 g/cm³at 20.0 ± 0.4°C, which is the mean of two values.

Precision of the value is given as maximal error of determination. Standard deviation was 0.0002 g/cm³, showing very good correlation of the two determinations.

Therefore, the study is considered valid.

Description of key information

Using the pycnometer method, a density of  1.6154 ± 0.0001 g/cm3 at 20 ± 0.4 °C was measured.

The relative density of the test item has the same number value, but no unit.

Key value for chemical safety assessment

Relative density at 20C:

1.615

Additional information

Using the pycnometer method, a density of  1.6154 ± 0.0001 g/cm³at 20 ± 0.4 °C was measured. This value is the mean of two independent determinations with the maximum error of a single determination. Standard deviation was 0.0002 g/cm³, showing very good correlation of the two determinations.
