Remarks on result:
other:
Remarks:
The sample melted and ignited when in contact with the ignition source, which was self-sustaining for 2 to 5 seconds with no propagation along the tray

The sample melted and ignited when in contact with the ignition source, which was self-sustaining for 2 to 5 seconds with no propagation along the tray.

Interpretation of results:
other: not classified based on EU CLP criteria
Conclusions:
Under the 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 test, the sample melted and ignited when in contact with the ignition source, which was self-sustaining for 2 to 5 s with no propagation along the tray. As in the preliminary screening test the sample was seen not to ignite, no further testing was required. Under the study conditions, the test substance was classified as not highly flammable (Chilworth, 2018).

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
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

Flammability of the test substance was determined according to EU Method A.10 (Chilworth, 2018).

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Justification for classification or non-classification

Based on the study results, the test substance does not warrant classification for flammability according to EU CLP (Regulation 1272/2008/EC).
