substances / mixtures which in contact with water emit flammable gases
Type of information:
experimental study
Adequacy of study:
key study
Study period:
17/07/2009 – 28/07/2009
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.12 (Flammability (Contact with Water))
Deviations:
no
GLP compliance:
yes
Test procedure:
other: Run 1: Mass of sample: 10 g
Max. rate of gas release:
12.4 L/kg h
Identity of evolved gas:
other: flammability of generated gas not tested
Remarks on result:
no reaction with water observed
Test procedure:
other: Run 2: Mass of sample: 10 g
Max. rate of gas release:
11.8 L/kg h
Identity of evolved gas:
other: flammability of generated gas not tested
Remarks on result:
no reaction with water observed
Test procedure:
other: Run 3: Mass of sample: 10 g
Max. rate of gas release:
8.5 L/kg h
Identity of evolved gas:
other: flammability of generated gas not tested
Remarks on result:
no reaction with water observed

The sample was observed to react slowly with water forming a white solid. The generated gas was not tested for flammability, however mass spectrometer analysis conclusively indicated that the gas was carbon dioxide which is not flammable.

Interpretation of results:
non flammable

Remarks on result:
no ignition on contact with air (not further specified)

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.

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.

Description of key information

The sample was observed to react slowly with water forming a white solid. The generated gas was not tested for flammability,

however mass spectrometer analysis conclusively indicated that the gas was carbon dioxide which is not 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
