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
Key result
Test procedure:
ignition time on contact with air
Remarks on result:
no ignition within 5 minutes
Key result
Test procedure:
step 1
step 2
step 3
step 4
Remarks on result:
no reaction with water observed
Interpretation of results:
not classified based on GHS criteria
Conclusions:
The test item has been determined to be not highly flammable as it did not propagate combustion over the 200 mm of the preliminary screening test.

The test item has been determined to be non-hazardous as no gases were evolved in any of the four steps.

The test item has been determined to be non-pyrophoric as it did not spontaneously ignite during the test.
Executive summary:

Flammability (Solids). Not highly flammable, using a procedure designed to be compatible with Method A.10 Flammability (Solids) of Commission Regulation (EC) No 440/2008 of 30 May 2008.

Flammability (Contact with Water). Non-hazardous, using a procedure designed to be compatible with Method A.12 Flammability (Contact with Water) of Commission Regulation (EC) No 440/2008 of 30 May 2008.

Pyrophoric Properties. Non pyrophoric, using a procedure designed to be compatible with Method A.13 Pyrophoric Properties of Commission Regulation (EC) No440/2008 of 30 May 2008.

Description of key information

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Justification for classification or non-classification

The substance has been determined to be not highly flammable as it did not propagate combustion over the 200 mm of the preliminary screening test in a study according to EU method A.10 for flammable solids.

The substance has been determined to be non-hazardous in contact with water as no gases were evolved in any of the four steps in a study according to EU method A.12.

The substance has been determined to be non-pyrophoric as it did not spontaneously ignite during a test according to EU method A.13.

On the basis of the results from these three studies, the substance should not be classified as flammable, according to the criteria set out in Regulation (EC) No 1272/2008.
