Flammable solids
Test procedure:
burning rate test: preliminary screening test
Burning time:
2 s

Any other information on results incl. tables

The flame of the gas burner did ignite the test item pile. The test item melted, burned with a blue yellow flame and turned into a black residue. Grey smoke was observed. After removal of the ignition source, the flame extinguished after 2 seconds and no propagation of combustion was observed.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The preliminary screening test was performed for the determination of the flammability of 3,4-dihydro-2,4-dioxo-1,3-2h-benzoxazine.
No propagation of combustion of the test item along 200 mm length of the pile within 4 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained, the test item is considered ‘not highly flammable’.
