- key study
- Study period:
- From April 11, 2006 to June 27, 2006
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- 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
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- Under the study conditions, the test substance was not a readily combustible solid.
- 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 commercial 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 project 2 mm beyond the upper edge of the triangular cross section. The mould was then dropped three times from a height of 2 cm onto a solid surface. The mould was then 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.
Reference
The test substance could not be ignited with a flame in the preliminary test. Therefore the main test was not performed.
Description of key information
The test substance is not a readily combustible solid (Smeykal, 2006).

Justification for classification or non-classification
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
