Link to relevant study record(s)
- Endpoint:
- density, other
- Remarks:
- Density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 23.10.2017 - 26.10.2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Study was performed in accordance with GLP requirements and no deviations were observed.
- Justification for type of information:
- Guideline study as required by REACH regulation 1907/2006
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Version / remarks:
- • OECD Guidelines for the Testing of Chemicals, Method No. 109, adopted 02. Oct. 2012: “Density of Liquids and Solids “
- Deviations:
- not specified
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Version / remarks:
- • Council Regulation (EC) No 440/2008 from 30 May 2008, published on 31. May 2008, Method A.3: “Relative Density”
- Deviations:
- not specified
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- pycnometer method
- Key result
- Type:
- density
- Density:
- >= 2.039 - <= 2.041 g/cm³
- Temp.:
- 20 °C
- Remarks on result:
- other: n=2 measurements, Standard deviation is: 0.0116 g/cm³
- Conclusions:
- The density of the test item was calculated as 2.0401 ± 0.0009 g/cm³ at 20.0 ± 0.2°C
- Executive summary:
According to OECD 109, using the pycnometer method, a density of 2.0401 ± 0.0009 g/cm³ at 20.0 ± 0.2°C was measured.
This value is the mean of two independent determinations with the maximum error of a single determination.
Standard deviation was 0.0116 g/cm³, showing good correlation of the two determinations.
Therefore, the study is considered valid.
The relative density of the test item has the same number value, but no unit, assuming that relative density is given as the ratio of test item density to density of water at 4°C, having a standard density of 0.999975
g/cm³ (source: CRC Handbook of Chemistry and Pyhsics - 90th edition / Section 6 - Fluid properties - p.6 -7).

Additional information
The density of the substance, determinded by pycnomter method, was calculated as 2.0401 ± 0.0009 g/cm3 at 20.0 ± 0.2°C.
This value is the mean of two independent determinations with the maximum error of a single determination.
Standard deviation was 0.0116 g/cm3, showing good correlation of the two determinations.
The relative density of the test item has the same number value, but no unit, assuming that relative density is given as the ratio of test item density to density of water at 4°C, having a standard density of 0.999975 g/cm³ (source: CRC Handbook of Chemistry and Pyhsics - 90th edition / Section 6 - Fluid properties - p.6 -7).
