Administrative data
- Endpoint:
- viscosity
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- from 16-12-2013 to 01-12-2014
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Remarks:
- Test method is according to APAG-FA-004 (industry standard, not guideline, but similar). Test substance adequately specified. Considered sufficient for classification purpose. Therefore validation applies, with restrictions, as not GLP, and lack of experimental details.
Cross-reference
- Reason / purpose for cross-reference:
- reference to other study

Applicant's summary and conclusion
- Conclusions:
- Fluid liquid.
Relevant for potential aspiration hazard (expected < 20.5 mm2/s at 40°C). - Executive summary:
The viscosity of the test substance was determined according to APAG-FA-004 method, with a Brookfield viscometer. Duplicate measurements were performed at each temperature, respectively 20 and 24°C. The mean value of 17 mPa.s at 20°C was retained.
