Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- pycnometer method
- Type:
- relative density
- Density:
- 1.188 other: dimensionless
- Temp.:
- 20 °C
- Conclusions:
- The relative density at 20 °C of the test item was determined as D4/20 = 1.188.
- Executive summary:
According to the OECD Guideline 109 (Density of Liquids and Solids) corresponding to A.3., Council Regulations EC No 440/2008 the solid sample of the test item was accurately weighed into a pycnometer and by displacement of the solvent (n-heptan), its equivalent volume was determined. Finally, the density of the sample was calculated. The relative density at 20 °C of the test item was determined as D4/20 = 1.188.
