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.

Preparation: sample tested as received

Apparatus: pyrophoric liquid system

Test information:

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.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
No reaction was observed in any test. Therefore, the sample is not a pyrophoric liquid.
Endpoint:
substances / mixtures which in contact with water emit flammable gases
Type of information:
experimental study
Adequacy of study:
key study
Study period:
16/12/2014 – 23/12/2014
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Conducted at a GLP accredited laboratory
Qualifier:
according to
Guideline:
EU Method A.12 (Flammability (Contact with Water))
Deviations:
no
GLP compliance:
yes
Test procedure:
other: 10 g of the sample was charged to a round bottom flask. The test was conducted three times.
Identity of evolved gas:
not applicable as no gas evolved
Remarks on result:
no reaction with water observed
Remarks:
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.
Interpretation of results:
non flammable
Conclusions:
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.

Description of key information

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.

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

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.

The test substance is considered to be:

*not flammable in contact with water

*not pyrophoric
