Applicant's summary and conclusion

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The preliminary screening test at room temperature and at 100°C was performed for the determination of the flmmability of SULFOBUTYL TMBI.
No propagate combustion of the test substance along 200 mm length of the pile within 4 minutes was observed. Based on this, the test substance was not considered as highly flammable and is classified as Class 2 "Brief ignition and rapid extinction".
