Applicant's summary and conclusion

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
With a minimum burning time for 100 mm of 101 s (maximum burning rate: 0.99 mm/s), the test item is not a highly flammable solid.

Executive summary:

The test substance was not a highly flammable solid in a guideline study on the burning time (maximum: 0.99 mm/s).
