Executive summary:

The study, entitled “Determination of Flammability of trans-2,3-Dibromo-2-Butene-1,4-Diol” was performed in compliance with the Study Plan No. P/PCP2641/FLM-S/18, which incorporated the recommendations made in the Guideline: OPPTS 830.6315. Preliminary screening test was performed prior to burning rate test for determination of flammability of test item. The test item was formed into an unbroken powder train, about 250 mm long using a mould and the pile of test item was ignited in fume hood. A hot flame from a gas burner was applied to one end of the powdered train for 2 minutes. The test item did not ignite and started melting after applying flame for 2 minutes.

The test item did not ignite and propagate combustion along 200 mm of powder train within 4 minutes. Hence the test item was not considered as highly flammable. As the test item was found to be non flammable in preliminary test the burning rate test was not performed. Based on the results obtained from the study, trans-2,3-Dibromo-2-Butene-1,4-Diol is considered

as non flammable.
