Test Results - Initial Tests

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

 

Test Results - Final Test

No gas generation or spontaneous ignitions were observed during any of the tests. The sample does not generate flammable gases in contact with water.

 

Assessment of Pyrophoric Properties

The sample was handled and opened to air during testing at Chilworth Technology Ltd. No spontaneous ignition of the sample was observed. The sample is therefore not considered to be pyrophoric.

 

Interpretation of results:
other: No gas generation or spontaneous ignitions were observed
Conclusions:
MEA-LAS do not generate flammable gases in contact with water. No gas generation or spontaneous ignitions were observed during any of the tests (EU Method A.12 (Flammability (Contact with Water))).
Executive summary:

A study was conducted to determine the ability of MEA-LAS to emit flammable gases upon contact with water following EU Method A.12 (Flammability (Contact with Water)).

The method consists of three preliminary tests to determine if a violent reaction with water occurs and a final test to determine the quantity of gas generated.

No gas generation or spontaneous ignitions were observed during any of the initial or final tests. The sample does not generate flammable gases in contact with water. The sample was handled and opened to air during testing. No spontaneous ignition of the sample was observed. The sample is therefore not considered to be pyrophoric.

 

MEA-LAS do not generate flammable gases in contact with water.

This flammability test is classified as acceptable, and satisfies the guideline requirements of the EU Method A.12 (Flammability (Contact with Water).

Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From Oct 13, 2011 to Nov. 28, 2011
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.10 (Flammability (Solids))
Deviations:
no
GLP compliance:
yes (incl. certificate)
Remarks:
according to OECD and EU principles of GLP
Key result
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

From the preliminary screening test the sample was seen not to ignite. Therefore no further testing was required

Interpretation of results:
other: Not highly flammable
Conclusions:
MEA-LAS was classified as not highly flammable (A.10 (Flammability (Solids)).
Executive summary:

The flammability of MEA-LAS was determined following EU Method A.10 (Flammability (solids)).

The sample was filled into a mould 250 mm long with a triangular cross section of height 10 mm and width 20 mm. After tapping the mould, to settle down the powder, it is inverted onto an impervious non-combustible plate of low thermal conductivity. The mould was removed and the ignition source was placed at one end of the powder train for 2 minutes or until the powder ignites.

The sample melted but no flame or propagation was observed. As the sample was seen not to ignite, therefore no further testing was required.

MEA-LAS was classified as not highly flammable (A.10 (Flammability (Solids)).

This flammability test is classified as acceptable, and satisfies the guideline requirements of the EU Method A.10.

Description of key information

The flammability of MEA-LAS was determined following EU Method A.10 (Flammability (Solids)). Additionally, a study was conducted to determine the ability of MEA-LAS to emit flammable gases upon contact with water following EU Method A.12 (Flammability (Contact with Water)).
