Endpoint:
auto-flammability
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2008-11-24 until 2009-09-17
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: GLP guideline study (EC)
Qualifier:
according to guideline
Guideline:
EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
Deviations:
yes
Remarks:
1. Instead of using two thermo elements, four were used to yield a better result for the detection of the ignition point. 2. The measurements in the main studies were not started at -5 K below the last determined resultbut only in approximation. | The dev
GLP compliance:
yes (incl. QA statement)
