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

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The substance is determined to not be highly flammable.

Executive summary:

The flammability of the substance was determined in accordance with EC A.10 and UN N.1. The substance was found not to be highly flammable, as the preliminary screening study found that combustion was not propagated.

Reference 2

Endpoint:

pyrophoric solids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Reference 3

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water

Description of key information

The flammability of the substance was determined in accordance with EC A.10 and UN N.1. The substance was found not to be highly flammable, as the preliminary screening study found that combustion was not propagated.

The substance is not highly flammable in contact with water as it does not contain groups that might lead to ignition in contact with water and/or the emission of a flammable gas.

The substance has no pyrophoric properties as it does not contain groups that might lead to ignition in contact with air.
