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
In contact with the ignition source, a strong red glowing of beryllium metal powder was observed which turned into a bright glowing circle after 4 minutes. Once the bright circle extinguished, a white residue remained, the rest of beryllium metal powder remained unchanged.
Beryllium metal powder could not be ignited with a flame during the preliminary test (contact time of about 5 minutes).
Therefore, no main test was performed.Applicant's summary and conclusion
- Conclusions:
- Based on the results of this study, beryllium metal powder would not be considered as "highly flammable" according to the criteria of the guideline.
- Executive summary:
The determination of the flammability of the test item was performed in accordance with the Council Regulation (EC) No. 440/2008, 30 May 2008, Part A, Methods for the determination of physico-chemical properties, A. 10 “Flammability (solids)”.
