Results and discussion

Pyrophoric solids

Test procedure:

ignition time on contact with air

Remarks:

Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).

Remarks on result:

no ignition on contact with air (not further specified)

Remarks:

corresponding to 'no' in migrated source record.

Pyrophoric liquids

Test procedure:

Remarks:

Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).

Remarks on result:

no ignition on contact with air (not further specified)

Remarks:

corresponding to 'no' in migrated source record.

Any other information on results incl. tables

Preliminary screening test:

The rope ignited and burned with a yellow flame which produced grey smoke and left charred remains and orange liquid. Combustion was propagated over 200 mm of the rope in 11 minutes and 24 seconds.

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

Mean moisture content (% w/w)	1.342

Applicant's summary and conclusion

Interpretation of results:

other: determined to be 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 rope 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.
