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

Two tests were performed: on each test, the same sample behaviour was observed. The sample tested did not ignite, but it melted became orange colour when the Bunsen's burner flame was approached. At room temperature it become a dark orange solid. The combustion did not propagate, therefore no further testing was required. The CAN 3 sample was not flammable.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The CAN 3 sample was not flammable.

Executive summary:

The sample was formed into a powder train 250 mm long, 20 mm wide, 10 mm high on a stainless-steel plate. A Bunsen flame is applied for a maximum of 2 minutes (or until ignition). It must be tested whether combustion propagates, either by burning with flame or smouldering along 200 mm of the powder train within the 4 minutes test period. Two tests were performed: on each test, the same sample behaviour was observed. The sample tested did not ignite, but it melted became orange colour when the Bunsen's burner flame was approached. At room temperature it become a dark orange solid. The combustion did not propagate, therefore no further testing was required. The CAN3 sample was not flammable.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

The sample tested did not ignite, but it melted became orange colour when the Bunsen's burner flame was approached. At room temperature it become a dark orange solid. The combustion did not propagate, therefore no further testing was required. The CAN3 sample was not flammable.
