Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Principles of method if other than guideline:
The substance is formed into an unbroken strip about 250 mm long and a preliminary screening test performed to determine if, on ignition by a gas flame, propagation by burning with flame or smouldering occurs. If propagation over 200 mm of the train occurs within a 4 minutes then a full test programme to determine the burning rate is carried out.

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:
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.

Any other information on results incl. tables

A.10. Flammability preliminary screening test: Negative

No ignition occurred on ignition by a gas flame for 2 minutes.

Applicant's summary and conclusion

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
The substance should not be considered highly flammable.
Executive summary:

In a study according to EU test method A.10, the substance could not be ignited by a gas flame for 2 minutes should therefore not be considered highly flammable.
