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
No ignition but swelling was observed in contact with a flame. After application of a hot platiin wire short ignition without spreading could be recorded.
Combustion Class Number (BZ = Brennzahl) 2 was assigned: short ignition and rapid extinction (definition according to Directive VDI 2263, Part 1)
Determination of burning rate was not required
Applicant's summary and conclusion
- Interpretation of results:
- non flammable
- Remarks:
- Migrated information
- Conclusions:
- Combustion Number (BZ) 2 was determined. Therefore, the substance has not to be classified as highly flammable solid according to Regulation (EC) No 1272/2008.
