flammable solids
Type of information:
experimental study
Adequacy of study:
key study
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)
Specific details on test material used for the study:
The test item was tested as received. No further preliminary treatment such as drying or milling was performed. The results given in this report only apply to the tested sample.
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
Interpretation of results:
GHS criteria not met
The flammability was determined according to a scientifically valid method (EU method A.10) under GLP, in a well-documented study, hence, the following result for the test material can be considered as reliable:
The test item is not a highly flammable solid in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.10.
No observations were made which might cause doubts concerning the validity of the study outcome.
The substance does not need to be classified as flammable solid.
Executive summary:

The flammability of the test item was determined following EU-Method A.10 under GLP.

In the preliminary screening test following the EU method, the burning behaviour over a distance of 200 mm is measured. One end of the pile is ignited. The test item could not be ignited with a flame, the test item melted and hence, the performance of the main test was not necessary.

Therefore, the test item should be considered as not-highly flammable solid (for EU regulations).

Description of key information

The test item could not be ignited with a flame during the preliminary test. The test item melted. The performance of the main test was not necessary, substance is not a highly flammable solid. [exp. result, GLP, EU A.10, 2016]
