Key result

Test procedure:

burning rate test: preliminary screening test

Remarks on result:

not determinable

Remarks:

The test item did not ignite and propagate combustion either by burning with a flame or smoldering along 200 mm within 4 minutes, the test item is not considered as highly flammable and no further testing is required.

The pile failed to ignite during the 2 minutes that the Bunsen flame was applied.

The result of the preliminary screening test obviated the need to perform the main test.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The test item has been determined to be not highly flammable as it failed to ignite in the preliminary screening test.

Executive summary:

The flammability (solids) was determined using a procedure designed to be compatible with Method A.10 Flammability (Solids) of Commission Regulation (EC) No 440/2008 of 30 May 2008, in accordance with GLP.

Under the conditiones of the study, the test item failed to ignite, therfore it was determined that the test item was not highly flammable.

Description of key information

Flammability (Solids)

The flammability (solids) was determined using a procedure designed to be compatible with Method A.10 Flammability (Solids) of Commission Regulation (EC) No 440/2008 of 30 May 2008, in accordance with GLP.

Under the conditiones of the study, the test item failed to ignite, therfore it was determined that the test item was not highly flammable.

Flammability (Contact with Water)

The flammability (Contact with Water) was visually assessed and predicted negative based on experience with handling and use of the test item.

.

Pyrophoric Properties of Solids

Pyrophoric Properties (of Solids) of the test item were visually assessed and predicted negative based on experience with handling and use of the test item.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

Flammability (Solids)

The determination was carried out by measuring the burning rate of test item prepared as a pile of set dimensions, using a procedure designed to be compatible with Method A.10 Flammability (Solids) of Commission Regulation (EC) No 440/2008 of 30 May 2008.

The test item has been determined to be not highly flammable as it failed to ignite in the preliminary screening test.

Flammability (Contact with Water)

Based on experience in handling and use of the test item, the flammability (contact with water) has been predicted negative.

Pyrophoric Properties of Solids

Based on experience in handling and use of the test item, the pyrophoric properties have been predicted negative.
