Results and discussion

Flammable solids
Key result
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

Any other information on results incl. tables

The test item1,4-Dithiothreitol (CAS no.3483-12-3) did not ignite at room temperature using a flame as ignition source being applied for at least 2 minutes. The test item melted. Thus, the performance of the main test was not necessary.

Applicant's summary and conclusion

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The test item 1,4 Dithiothreitol (CAS no. 3483-12-3) could not be ignited applying a flame as ignition source for at least 2 minutes. Therefore, the product should not be classified as readily combustible solid in class 4, Division 4.1 according to the UN Transport Regualtion or as flammable solid according to the GHS/CLP Regulation EC 1272/2008 Annex 1: 2.7.
Executive summary:

The test item 1,4 Dithiothreitol (CAS no. 3483-12-3) could not be ignited applying a flame as ignition source for at least 2 minutes. Therefore, the product should not be classified as readily combustible solid in class 4, Division 4.1 according to the UN Transport Regualtion or as flammable solid according to the GHS/CLP Regulation EC 1272/2008 Annex 1: 2.7.
