EC number: 701-029-8 | CAS number: -
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.
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
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
Interpretation of Results:
If the sample ignites in any one of the tests, the material should be considered pyrophoric.
Preparation: sample tested as received
Apparatus: pyrophoric liquid system
a small quantity of the sample (1 -2 ml) was dropped from a height of approx. 1 meter onto a non-combustible surface. It was observed if the sample ignited on dropping or within 5 minutes of settling. The test was performed six times.
No gas generation or spontaneous ignitions were observed during any of the tests.
The sample does not generate flammable gases in contact with water and is therefore Non-hazardous.
