Endpoint:
substances / mixtures which in contact with water emit flammable gases
Type of information:
experimental study
Adequacy of study:
key study
Study period:
17/06/2009 - 26/06/2009
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:
0.11 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:
0.37 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:
0.35 L/kg h
Identity of evolved gas:
other: flammability of generated gas not tested
Remarks on result:
no reaction with water observed

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).

Interpretation of results:
not classified based on GHS criteria
Conclusions:
Does not emit flammable gases in contact with water.
Endpoint:
pyrophoric liquids

Guideline:
EU Method A.13 (Pyrophoric Properties of Solids and Liquids)
GLP compliance:

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

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
