Link to relevant study record(s)
- Endpoint:
- viscosity
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2008.06.16, 2008.06.23
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- other: DIN 51562
- Deviations:
- no
- Principles of method if other than guideline:
- The method used is adapted from the DIN method 51562 (1999-01) "Ubbelode". The measurement was carried out measuring the time the test material needs to fill the defined distance in the capillary of the UBBELODE viscosimeter.
- GLP compliance:
- no
- Remarks:
- Instead: DIN EN ISO 9001: 2000 management system certification (incl. certificate), TUEV NORD CERT GmbH, Germany
- Type of method:
- capillary viscometer (static)
- Temp.:
- 20°C
- Parameter:
- kinematic viscosity (in mm²/s)
- Value:
- ca. 7.875
- Executive summary:
In this study the viscosity of the test substance 3 -mercaptopropionic acid has been determined to be 7.875 mm2/s at 20 °C (293.15 K) by using capillary viscosimeter, regarding method described in DIN 51562 as of 1999.
