 Parameter  Value  Unit  Standard Deviation  Relative Standard Deviation
 Volume of Pycnometer  24.91  cm3  0.0060  0.02%
 Density of Test Item  1.6777  g/cm3  0.0003  0.02%
  Density of Test Item  1677.7  kg/m3  0.3  0.02%
 Relative Density of Test Item  1.6777    0.0003  0.02%
Conclusions:
The density of the test item was calculated as 1.6777 ± 0.0011 g/cm3 at 20.0 ± 0.4 °C, which is the mean of two values. Precision of the value is given as maximal error of a single determination.
The relative density of the sample at 20 °C to water at 4 °C is 1.6777.
Executive summary:

The density of the test item was calculated as 1.6777 ± 0.0011 g/cm3 at 20.0 ± 0.4 °C, which is the mean of two values. Precision of the value is given as maximal error of a single determination. Standard deviation was 0.0003 g/cm3, showing very good correlation of the two determinations. Correspondence of the values is very good. Therefore, the study is considered valid. The relative density of the sample at 20 °C to water at 4 °C is 1.6777.

The study was performed under GLP according to OECD guildeline 109 and to EU Method A.3.

Description of key information

The density of the test item was calculated as 1.6777 ± 0.0011 g/cm3 at 20.0 ± 0.4 °C, which is the mean of two values. Precision of the value is given as maximal error of a single determination. Standard deviation was 0.0003 g/cm3, showing very good correlation of the two determinations. Correspondence of the values is very good. Therefore, the study is considered valid. The relative density of the sample at 20 °C to water at 4 °C is 1.6777.

The study was performed under GLP according to OECD guildeline 109 and to EU Method A.3.
