- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- September 05, 2011 - November 08, 2011
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- Study performed according to international guidelines giving scientifically valid results but not under GLP
- Reason / purpose for cross-reference:
- reference to same study
- Reason / purpose for cross-reference:
- reference to other study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Version / remarks:
- (May 2008)
- Deviations:
- not specified
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Version / remarks:
- (July 1995)
- Deviations:
- not specified
- Principles of method if other than guideline:
- The oscillating densitimeter method was employed to determine the density of the sample. A mechanical oscillator constructed in the form of a U-tube is vibrated at the resonance frequency of the oscillator which depends on its mass. The method is applicable to liquids with a dynamic viscosity below 5 Pa.s.
The relative density is the quotient of the mass of a defined volume of test item, measured at 20°C, and the mass of the same volume of water determined at 4°C. Relative density 20°C/4°C of the test item = density of the test item at 20°C [kg/m3]/999.975 [kg/m3] (density of water at 4°C)
Three measurements were performed at 20°C+/-0.5°C. - GLP compliance:
- no
- Type of method:
- oscillating densitimeter
- Type:
- relative density
- Density:
- ca. 0.858 g/L
- Temp.:
- 20 °C
- Remarks on result:
- other: Relative density D20°C/4°C. Results obtained from three measurements of density at 20°C+/-0.5°C
- Conclusions:
- The relative density of (-)-alpha-pinene was determined to be 0.858.
- Executive summary:
The test to determine the relative density of (-)-alpha-pinene was conducted in compliance with OECD guideline 109 and the EU method A.3. Three measurements with a oscillating densitimeter gave a value of 0.858 for the relative density of (-)-alpha-pinene.
The test was performed in compliance with OECD guideline 109 and gives scientifically valid results. As no observations were made which might cause doubts concerning the validity of the study outcome, the results of the study were considered valid.

Description of key information
The relative density of (-)-alpha-pinene was determined to be 0.858.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.858
Additional information
The relative density of (-)-alpha-pinene at 20°C was determined in a study performed according to OECD Guideline 109 and EU method A3 using an oscillating densimeter. The value was considered with a reliability of 2 (reliable with restrictions) because the result is scientifically acceptable but not obtained under GLP and some details were lacking in the report.
The relative density obtained is valid for key value and supported by consistent experimental data on alpha-pinene multiconstituent.
