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
The test substance is assigned to combustion class BZ 3 (local burning without spread) at room temperature and at 100 °C.
As the flame does not propagate no burning rate can be determined.
Applicant's summary and conclusion
- Interpretation of results:
- non flammable
- Remarks:
- Migrated information
- Conclusions:
- The test substance is assigned to combustion class BZ 3 (local burning without spread) at room temperature and at 100 °C. The test substance is not a flammable solid according to the UN transport regulations class 4.1.
- Executive summary:
The flammability of the test substance was evaluated by the determination of the combustion class number ("Brennzahl" BZ) according to company guideline. The test substance is assigned to combustion class BZ 3 (local burning without spread) at room temperature and at 100 °C. The test substance is not a flammable solid.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
