Referenceopen allclose all
No significant gas generation was observed over the initial 7 hour test period. Slow gas generation was observed to start after approximately 10 hours and a pale yellow solid formed at the bottom of the flask. The maximum rate of gas generation (0.87 l.kg-1.h-1) was observed in Run 2 approximately 20 hours after adding the water. The generated gas was not tested for flammability (anticipated to be carbon dioxide – non-flammable).
The test is designed to determine the ability of a solid or liquid to ignite on contact with air.
The test is conducted in accordance with EC 440/2008 incorporating EC’s “Classification,
Packaging & Labelling of Dangerous Substances in the European Union” Part 2, Testing
methods, Jan ’97. Directive 92/69, Annex V to Council Directive 67/548/EC.
Test Procedure:
Solids
1-2 ml of the powdery substance to be tested is poured from a height of 1 metre onto a
non-combustible surface and it is observed whether the substance ignites during dropping
or within 5 minutes of settling. The test is performed six times unless a positive result is
obtained earlier.
Liquids
Two separate tests are conducted. The first involves filling a porcelain cup of about
100 mm diameter with diatomaceous earth or silica gel to a height of 5 mm. 5 ml of the
substance to be tested is added and it is observed if the substance ignites within
5 minutes. The test is performed six times unless a positive result is obtained earlier. If the
result is negative then the second test is conducted. This involves placing 0.5 ml of the
substance in the centre of a dry filter paper. It is observed if ignition or charring occurs
within five minutes. The test is performed three times unless a positive result is obtained
earlier.
Interpretation of Results:
If the sample ignites in any one of the tests, the material should be considered pyrophoric.
Description of key information
No significant gas generation was observed over the initial 7 hour test period. Slow gas generation was observed to start after approximately 10 hours and a pale yellow solid formed at the bottom of the flask. The maximum rate of gas generation (0.87 l.kg-1.h-1) was observed in Run 2 approximately 20 hours after adding the water. The generated gas was not tested for flammability (anticipated to be carbon dioxide – non-flammable).
The test substance is considered to be:
*not flammable in contact with water
*not pyrophoric
Key value for chemical safety assessment
- Flammability:
- not classified

Justification for classification or non-classification
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.
