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

The test item melted to a light yellow liquid. No burning occurred within two minutes. No signs of flammability was observed. Since ignition did not occur within two minutes, the test item was classified as not highly flammable (for EU regulations) and non-flammable solid (for UN regulations), resp. no determination of burning rate was necessary.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The substance ROC-601 was found to be not highly flammable and thus not subject to classification as flammable solid.

Executive summary:

No ignition was observed throughout the course of the test. The test item ROC-601 should be considered as not highly flammable (for EU regulations) and non-flammable solid (for UN regulations), resp.

No observations were made which might cause doubts concerning the validity of the study outcome.

Reference 2

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

Reference 3

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

Description of key information

The test item melted to a light yellow liquid when treated with a gas burner. No burning occurred within two minutes. No signs of flammability were observed. Since ignition did not occur within two minutes, the test item was classified as not highly flammable (for EU regulations) and non-flammable solid (for UN regulations), resp. no determination of burning rate was necessary.

From experience in handling and use it is known that the substance is stable in air (non pyrophoric) and does not react with water to form flammable gases.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

Since the substance could not be ignited with a gas burner upon 2 minutes of exposure, the substance is considered not highly flammable and thus not subject to classification as flammable solid according to CLP (Regulation EU No 1272/2008). Classification for pyrophoricity or reactivity with water to form flammable gases is not required based on experience in handling and use of the substance.
