Results and discussion

Flammable solids
Key result
Test procedure:
burning rate test: preliminary screening test
Burning time:
1 s

Any other information on results incl. tables

The flame of the gas burner did ignite the test material pile. The test material melted, burned with an orange flame, and turned into a black residue. Thick grey smoke was observed. After removal of the ignition source, the flame extinguished after 1 second and no propagation of combustion was observed.

Applicant's summary and conclusion

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The preliminary screening test was performed for the determination of the flammability of JNJ-61232574-AAA (T003630).
No propagation of combustion of the test material along 200 mm length of the pile within 2 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained, the test material is considered ‘not flammable’.
