Test results - initial test:

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

Test information - Final Test:

10 gr of the sample was charged to a round bottom flask which was connected to a pressure equalised dropping funnel containing 20 ml of water and an automated gas burette system. The water was then added rapidly to the flask. The rate and quantity of gas generated was measured for 7 hours or until the gas generation had ceased. the test was conducted three times.

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

Interpretation of results:
non flammable
Remarks:
The sample was observed to react slowly with water forming a white solid. The generated gas was not tested for flammability.
Conclusions:
Test Results for the test item: The sample was observed to react slowly with water forming a white solid. The generated gas was not tested for flammability.
The test item is Non-Hazardous.

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)

 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 was observed in 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 scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is a liquid
