Type of information:
experimental study
Adequacy of study:
key study
Study period:
From September 22, 2004 to September 30, 2004
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
EU Method A.10 (Flammability (Solids))
GLP compliance:
yes (incl. QA statement)
Key result
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

The test substance could not be ignited with a flame in the preliminary test. Therefore, the main test was not performed.

Interpretation of results:
not classified based on GHS criteria
Under the study conditions, the test substance was not found to be readily combustible.
Executive summary:

A study was conducted to determine the flammability of the test substance according to EU Method A.10, in compliance with GLP.

The test substance in its ground form was loosely filled into a mould. The mould was made of metal, with a length of 250 mm and a triangular cross section with an inner height of 10 mm and an inner width of 20 mm. On both sides of the mould, in a longitudinal direction two metal sheets were mounted as lateral limitations which projected 2 mm beyond the upper edge of the triangular cross section. After filling, the mould was dropped three times from a height of 2 cm onto a solid surface. If necessary the mould was filled up again. Then the lateral limitations were removed and the excess substance was scraped off. A non-combustible and non-porous plate was placed on top of the mould, the apparatus was inverted and the mould was removed. As ignition source, a flame was used to ignite the pile at one end.

The test substance could not be ignited with a flame in the preliminary test. Therefore the main test was not performed. Under the study conditions, the test substance was not a readily combustible solid.


Description of key information

The test substance is not a readily combustible solid (Franke, 2004).
