Specific details on test material used for the study:

Name: FAT20013/D TE Lot. 1502011

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

Safety Pre-Test: A small amount of the test item was heated on a magnesia groove with a gas burner. Glowing was observed. The test item showed signs of ignition.

Preliminary screening test

The test item was heated with the flame of a teclu burner. Glowing was observed during heating. An ignition and smouldering was occurred within two minutes, but the smouldering stop after a few seconds and a small distance. Nevertheless, the full test program was carried out. The test was performed six times, but no positive result was observed. In each trial the smouldering stop after a small distance.

Results:

No ignition was observed throughout the course of the test. The test item FAT20013/D should be considered as not highly flammable.

Interpretation of results:

GHS criteria not met

Conclusions:

No ignition was observed throughout the course of the test. The test item FAT 20013/D should be considered as not highly flammable.

Executive summary:

The flammability of the test substance was evaluated in a study conducted according to EU Method A.10. The test item FAT 20013/D should be considered as not highly flammable. The flammability of the test item was evaluated in a study conducted according to EU Method A.10. In this study, the test item was formed into an unbroken strip or powder train about 250 mm long. The pile was arranged at right angle to the draught in the fume cupboard. The flame of the gas burner was used to ignite the pile at one end. A stop watch was held ready. No ignition was observed throughout the course of the test. No ignition was observed throughout the course of the test. The test item FAT 20013/D should be considered as not highly flammable.
