Type of information:

experimental study

Adequacy of study:

key study

Study period:

22 Feb - 22 Feb 2002

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.12 (Flammability (Contact with Water))

Deviations:

no

GLP compliance:

Key result

Test procedure:

step 1

step 2

step 3

step 4

Remarks on result:

no reaction with water observed

Stage 1:
The test substance was added to a dish containing distilled water. No formation of reaction gases was observed. Attempts to ignite the gas phase above the dish with the flame of a burner produced negative results.

Stage 2:
The test substance was introduced to a filter paper floating on the surface of the destilled water contained in a dish. No formation of reaction gases was observed. Attempts to ignite the gas phase above the filter paper produced negative results.

 

Stage 3:

A few drops of water were added to a sample of the test substance. No formation of reaction gases was observed. Ignition attempts of the gas phase produced negative results.

 

Stage 4:

Water (ca. 20 mL) was added from a dropping funnel to the quantities of test substance specified below. One test run was performed.

The following total quantities of liberated gas were determined by using a miniature
gasometer.

	Test run 1
Test sample weights	10.0 g
Time	Total gas evolution rate
60 min	0 L/kg*h
120 min	0 L/kg*h
180 min	0 L/kg*h
240 min	0 L/kg*h
300 min	0 L/kg*h
360 min	0 L/kg*h
420 min	0 L/kg*h

Liberation of gas could not be observed after water addition was initiated.

 

Validity criteria for the measurement of the flammability:

Target condition according to guideline 92/69/EWG A. 12:	Actual condition according to the study:	Validity criteria met:
The report shall include the results of the tests (steps 1, 2, 3 and 4) and the chemical identity of gas evolved.	The results of the steps are stated. No gas evolution occured.	Yes
The rate of evolution of gas if step 4 is performed shall be stated.	No gas evolution occured.	Yes

 

Interpretation of results:

GHS criteria not met

Conclusions:

The test substance does not liberate gases in hazardous amounts when tested according to this procedure. The substance does not emit flammable gases on contact with water.

Executive summary:

The test substance does not liberate gases in hazardous amounts when tested according to this procedure. The substance does not emit flammable gases on contact with water.

Description of key information
