Specific details on test material used for the study:

Identification: FAT 40000/I TE Lot: MC 13
Appearance: Yellowish-orange powder

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

Findings

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:

GHS criteria not met

Conclusions:

No ignition was observed throughout the course of the test. Hence, the test item 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 was loosely filled into the mould. The mould was limited laterally by two metal plates. The mould was then dropped three times from a height of 2 cm onto a solid surface and then filled up again. The lateral limitations were removed and the excess substance was scraped off. The glass plate was placed on top of the mould, the apparatus was inverted and the mould removed.

The substance did not ignite or propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period. Hence, the test item should be considered as not highly flammable.

Description of key information

The test item should be considered as not highly flammable.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

The substance did not ignite or propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period. Hence, the test item should be considered as not highly flammable.

Justification for classification or non-classification

No ignition was observed throughout the course of the test. The test item should be considered as not highly flammable. Therefore, no classification is warranted according to CLP (1272/2008) Regulation.
