burning time (test type not further specified)
Remarks:
or specified in description of method (migrated information)
Burning time:
0 s

Any other information on results incl. tables

Preliminary screening test: The pile failed to ignite during the two minutes that the Bunsen flame was applied. The result of the preliminary screening test obviated the need to perform the main test.

Applicant's summary and conclusion

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
The test material has been determined to be not highly flammable as it failed to ignite in the preliminary screening test.
Executive summary:

The procedure for the preliminary screening test specified in Method A.10 Flammability (Solids) of Commission Regulation (EC) No 440/2008 of 30 May 2008 is the same as the procedure for the preliminary screening test specified in Test N.1 (test method for readily combustible solids) of the United Nations Recommendations on the Transport of Dangerous Goods manual of tests and criteria, fourth revised edition 2003. Test N.1 states that, if the substance does not ignite within the 2 minutes test period, then the substance should not be classified as a flammable solid and thus is not a readily combustible solid of Division 4.1.
