Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

yes

Key result

Test procedure:

burning rate test: preliminary screening test

Moisture (wt %):

0.85

Remarks on result:

other: Not highly flammable

Remarks:

The sample melted to a light brown liquid and ignited with a flame when in contact with the ignition source. No propagation observed.

Results

In the preliminary screening study, the test substance was melted to a light brown liquid and ignited with a flame when in contact with the ignition source. No propagation was observed. Based on the preliminary study results, the author concluded that no further main testing was required.

Interpretation of results:

other: Not classified based on EU CLP criteria

Conclusions:

Under study conditions, the test substance was classified as not highly flammable.

Executive summary:

A study was conducted to determine the flammability of the test substance, according to EU method A.10, in compliance with GLP. In the preliminary screening study, the test substance melted to a light brown liquid and ignited with a flame when in contact with the ignition source. No propagation was observed. Based on the preliminary study results, the author concluded that no further main testing was required. Under study conditions, the test substance was classified as not highly flammable (Chilworth, 2017).

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 flammability of the test substance was determined, according to EU method A.10 (Chilworth, 2017).

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

In the preliminary screening test, the test substance melted to a light brown liquid and ignited with a flame when in contact with the ignition source. No propagation was observed; therefore no further study was conducted. Based on the study results, the test substance does not warrant classification for flammability according to the EU CLP criteria (Regulation 1272/2008/EC).
