Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- September 2009
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Well conducted study, under Internal Management System, according to OECD Guideline 109. Certificate of analysis included in the report.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Version / remarks:
- section 9
- Qualifier:
- according to guideline
- Guideline:
- other: DIN 51913Determination of density by gas pycnometer (volumetric) using Helium gas as the measuring gas – Solid materials, May 2001
- Deviations:
- yes
- Remarks:
- Temperature 23°C instead of 20°C.
- Qualifier:
- according to guideline
- Guideline:
- other: ISO1183-3, Plastics. Methods for determining the density of non-cellular plastics – Part 3: Gas Pyknometer method, 1999
- Principles of method if other than guideline:
- In the procedure a measuring temperature of 20°C is prescribed. In reality the measurement
is carried out at 23°C. However, based on the known thermal expansion factor of similar
chemicals, it can be stated that this deviation in measuring temperature has no significant
impact on the resulting relative density. - GLP compliance:
- no
- Type of method:
- pycnometer method
- Type:
- relative density
- Density:
- 1.04 g/cm³
- Temp.:
- 23 °C
- Remarks on result:
- other: RSD 0.16 %
- Conclusions:
- The relative density of dilauroyl peroxide is 1.04.
- Executive summary:
The study was conducted to determine the density of the substance by the pycnometer method accocding to DIN 51913. The relative density of di-lauroyl peroxide is 1.04.
