- key study
- Study period:
- 2009-01-12
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Principles of method if other than guideline:
- The measurement was carried out by oscillating densitometry using procedures described in DIN 51757, complying to method A3 of Commission Directive 440/2008/EC as of 30.05.2008 (which substitutes Council Directive 67/548/EEC) and method 109 (Art.11) of OECD testing guidelines for testing chemicals (27.07.1995).
Measurements are performed in compliance to ISO 9001 standards. The test report fully reflects the procedures and data generated. - GLP compliance:
- no
- Remarks:
- Instead: DIN EN ISO 9001: 2000 management system certification (incl. certificate), TUEV NORD CERT GmbH, Germany
- Type of method:
- oscillating densitimeter
- Type:
- relative density
- Density:
- ca. 1.28
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test material Pentaerytrityltetra (3-mercaptopropionate) (PETMP) has been determined to be 1.28327+/-0.00003 at 20 °C (293.15 K).
- Executive summary:
The test material Pentaerytrityltetra (3-mercaptopropionate) (PETMP) has been determined to have a relative density 1.28327+/-0.00003 at 20 °C (293.15 K) by using oscillating densitometry using procedures described in DIN 51757, complying to method A3 of Commission Directive 440/2008/EC as of 30.05.2008 (which substitutes Council Directive 67/548/EEC) and method 109 (Art.11) of OECD testing guidelines for testing chemicals (27.07.1995).
Reference
Triplicate determinations resulted in the values 1.2832, 1.2833 and 1.2833, mean value was reported as 1.28327 +/-0.00003 at 20 °C. The measured relative density of the test material sample differs lower than 0.01%. Compared to the found deviation of the value for the water calibration these findings are considered as accurate.

Additional information
In the experimental laboratory study the relative density of Pentaerytrityltetra (3 -mercaptopropionate) (PETMP) has been determined to be 1.28327 +/-0.00003 at 20 °C (293.15 K). Study was performed by using oscillating densitometry using procedures described in DIN 51757, complying to method A3 of Commission Directive 440/2008/EC as of 30.05.2008 (which substitutes Council Directive 67/548/EEC) and method 109 (Art.11) of OECD testing guidelines for testing chemicals (27.07.1995).
