Any other information on results incl. tables

During Step 1, no flame was observed when the electric match triggered (sparked) and ignited. A chemical odor was present but no obvious evolution of gas.

During Step 2, no flame was observed when the electric match triggered (sparked) and ignited. A chemical odor was present but no obvious evolution of gas.

During Step 3, boiling was observed when the drops of purified reagent water were added and evolution of a gas was observed. An electric match was ignited and the flame was placed over the opening over the vial. The flame was drawn into the vial, creating smoke. The vial was very hot and gas refluxes were observed on the sides of the vial. Step 3 was conducted two additional times for confirmation. Neither additional experiment was able to produce the same observations with the flame drawn into the vial.

The results for Step 4 are presented in Table 1 of the attached report. For the three tests, the temperature ranged from 17.4 to 22.0 fiC at initiation and 18.8 to 22.0 GC at termination. Since no erratic or increasing flow rate was observed, the test was terminated following 7 hours. The volume of gas emitted remained constant from test initiation through 7 hours (test termination) for all three tests.

Applicant's summary and conclusion

Interpretation of results:

non flammable

Remarks:

Migrated information

Conclusions:

Based on the results, it was determined that the test article is not flammable in contact with water.

Executive summary:

The purpose of this study was to determine whether the reaction of the test article with water or damp air leads to the development of dangerous amounts of gas or gases which may be flammable. Knowledge of the flammability of a test substance is necessary in order to determine its safety during shipping and usage. Test substances are considered to be highly flammable when, in contact with water or damp air, they evolve highly flammable gases in dangerous quantities at a minimum rate of 1 L/kg per hour.

The test substance did not ignite during Step 1, Step 2 and Step 3. An odor was present during Steps! through 3 but no evolution of gas was observed. During Step 4 no erratic or increasing flow rate was observed. Based on these results, it was determined that the test article is not flammable in contact with water.
