Results and discussion

Any other information on results incl. tables

 Results:

 Preliminary screening test:

The pile ignited and burnt with a red glow, which produced grey smoke and left a grey charred surface and a green powdered residue. Combustion was propagated over 200 mm in 4 minutes 31 seconds.

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

Applicant's summary and conclusion

Interpretation of results:
other: not highly flammable
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 in under 4 minutes.
Executive summary:

The flammability (solids) was determined by measuring the burning rate of test material prepared as a pile of set dimensions. Testing was conducted using Method A10 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC). 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 in under 4 minutes.
