Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2015

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Deviations:

no

GLP compliance:

no

Test procedure:

burning time over 250 mm for metal powders or metal alloys

Remarks:

or specified in description of method (migrated information)

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 no signs of ignition.

Preliminary screening test:

The test item was heated with the flame of a teclu burner. Glowing was observed during heating. No ignition occurred within two minutes.

Interpretation of results:

non flammable

Remarks:

Migrated information

Conclusions:

The test item FAT 20043/E should be considered as not highly flammable.

Executive summary:

This study was performed in order to determine the flammability FAT 20043/E as per EU method A.10 method. 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. Since ignition did not occur within two minutes, the test item was classified as not highly flammable and no determination of burning rate was necessary. Determination of Burning rate Not carried out as the test item showed no ignition. The following findings were noted:

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 no signs of ignition.

Preliminary screening test:

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

No ignition was observed throughout the course of the test. Hence, the test item FAT 20043 should be considered as not highly flammable. Thus, no classification is needed as per the CLP criteria.
