Results and discussion
Flammable solids
- 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
Any other information on results incl. tables
Results
Preliminary Screening Test
The pile melted but failed to ignite during the 2 minutes that the
Bunsen flame was applied. The result of the preliminary screening test
obviated the need to perform the main test.

Conclusion: The test item is not highly flammable as it failed to ignite in the preliminary screening test.
Applicant's summary and conclusion
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- The test item is not highly flammable as it failed to ignite in the preliminary screening test.
- Executive summary:
Flammability of the test item was measured using the EU A.10 test method.
A mould (250 x 20 x 10 mm) was loosely filled with test material (tested as received). A non-combustible, non-porous board was placed onto the mould which was then inverted. The mould was removed and an air-rich Bunsen burner flame applied to one end of the pile until ignition occurred. If combustion occurred, the time taken to propagate 200 m was recorded.
The moisture content was determined gravimetrically. An aliquot (ca. 1 g) of test material was weighed (in duplicate; A and B) into loss bottles. The samples were dried to constant weight under reduced pressure at ca. 40 °C over phosphorus pentoxide.
The test item is not highly flammable as it failed to ignite in the preliminary screening test.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
