Endpoint:
substances / mixtures which in contact with water emit flammable gases
Type of information:
experimental study
Adequacy of study:
key study
Study period:
23/09/2014
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Conducted at a GLP accredited laboratory to GLP
Qualifier:
according to
Guideline:
EU Method A.12 (Flammability (Contact with Water))
Deviations:
no
GLP compliance:
yes
Key result
Test procedure:
other: Mass: 10 gr.
Max. rate of gas release:
1 L/kg h
Identity of evolved gas:
as specified:
Remarks:
gas genarated was analysed using a mass spectrometer and was identified as Carbon Dioxide.
Remarks on result:
other: the sample does not generate flammable gases in contact with water and is therefore non-hazardous.

Test results - Initial test:

No gas generation or spontaneous ignitions were observed during any of the tests.

Test nformation - final test:

10 g of the sample was charged to a round bottom flask which was connected to a pressure equalised dropping funnel contaning 20mL of water and a automated gas burette system.

The water was then added rapidly to the flsk. the rate and quantity of gas generated was measured for 24 hours until the gas generation had ceased.

the test was repeated allowing a test duration of 60 hours until gas generation had ceased. The rate of gas evolution exceeded 1l.kg-1 therefore the gas generated was analysed using a mass spectrometer and was identified as carbon dioxide.

Test results - Final Test.

The sample does not generate flammable gases in contact with water and is therefore Non-hazardous.

Interpretation of results:
non flammable
Remarks:
Migrated information Liquid
Conclusions:
the sample does not generate flammable gases in contact with water and is therefore Non-Hazardous.
Endpoint:
pyrophoric liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Start date of the experimental work: 22/09/2014 and Completion date of the experimental work: 23/09/2014
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.13 (Pyrophoric Properties of Solids and Liquids)
GLP compliance:
yes
Test procedure:
other: Porselain Cup
Remarks on result:
no ignition on contact with air (not further specified)
Test procedure:
effect on filter paper
Remarks on result:
no charring
Test procedure:
effect on filter paper
Remarks on result:
no ignition on contact with air (not further specified)

Full test results for Porcelain cup:

 Test number Ignition Yes (y) / No (n)  Comments 
 1  n   No reaction
 2  n   No reaction
 3  n   No reaction
 4  n   No reaction
 5  n   No reaction
 6  n   No reaction

Full test results for filter paper:

 Test number   Ignition Yes (y) / No (n)   Charring Yes (y) / No (n) Comments 
 1  n  n   No reaction
 2  n  n   No reaction
 3  n  n  
 No reaction

No reaction or charring was observed during any test. Therefore, the sample is not a pyrophoric liquid.

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:
flammable liquids: obsolete as covered by section 'Flash point'
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a liquid

Description of key information

Method EU A.12: The sample was observed to react slowly with water forming a white solid. The generated gas was not tested for flammability.

Method EU A.13: Not a pyrophoric liquid.

The test sample is Non-Hazardous.

Key value for chemical safety assessment

Flammability:
not classified
