Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Version / remarks:

Deviations:
no
GLP compliance:
yes (incl. QA statement)
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
other: No propagation of combustion along 200 mm length of the powder train within 4 minutes was observed.

The flame of the gas burner did ignite the test substance pile. The test substance glowed, burned with a blue yellow flame and turned into a grey-black residue. Grey smoke was observed. After removal of the ignition source, the flame extinguished immediately and no propagation of combustion was observed.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
In a GLP-compliant study performed in accordance with UN-MTC Section 33.2.1 (Test N.1) and EC.A10, the substance has been determined to be 'not highly flammable'.
Executive summary:

In a GLP-compliant study performed in accordance with UN-MTC Section 33.2.1 (Test N.1) and EC.A10, the preliminary screening test was performed for the determination of the flammability of test item.

No propagation of combustion of the test substance along 200 mm length of the pile within 4 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained, the test substance is considered ‘not highly flammable’.

GLP compliance:
yes (incl. QA statement)
Test procedure:
ignition time on contact with air
Remarks on result:
no ignition within 5 minutes
Remarks:
In none of the six tests, no spontaneous ignition of the test sample occurred during dropping or within five minutes of settling.

Additional information

Justification for classification or non-classification

Flammable solids:

EC.A10, No propagation of combustion of the test substance along 200 mm length of the pile within 4 minutes was observed.

Therefore in accordance with Regulation (EC) No. 1272/2008 section 2.7.2.1, this substance should not be classified as flammable solids.

Flammability in contact with water:

EC A12, No evolution of a gas and/or spontaneous ignition of the test substance in contact with water was observed in Test 1, Test 2, Test 3 and Test 4.

Therefore, in accordance with Regulation (EC) No. 1272/2008 section 2.12.2.2, the substance is not classified as a substance which in contact with water emits flammable gases.

 

Pyrophoric solids:

EC.A13, the test item did not spontaneously ignite during dropping or within five minutes of settling.

Therefore, in accordance with Regulation (EC) No. 1272/2008 table 2.10.1, the substance should not be classified as pyrophoric solids.
