Any other information on results incl. tables

Results

Preliminary screening test

The pile ignited with a smoky orange flame, which self-extinguished 2 seconds after the Bunsen flame was removed, without propagating combustion.

The result of the preliminary screening test obviated the need to perform the main test.

Conclusion

The test material has been determined to be not highly flammable as it did not propagate combustion over the 200 mm of the preliminary screening test.

Applicant's summary and conclusion

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
The test material has been determined to be not highly flammable as it did not propagate combustion over the 200 mm of the preliminary screening test.
Executive summary:

For substance Na-Na in project number 1307 -0437 the flammability (solids) was determined by measuring the burning rate of test material prepared as a pile of set dimensions.  The test material has been determined to be not highly flammable as it did not propagate combustion over the 200 mm of the preliminary screening test. Testing was conducted using Method A10 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).
