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

In the preliminary test the test item melted and could not be ignited. Based on the results of the preliminary test, no main test was performed.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The test item is non-flammable in the conditions of this test.

Description of key information

The tests were negative. The test item is non-flammable in the conditions of this test.

Justification for classification or non-classification

In the preliminary test, the test item melted and could not be ignited. Since the tests were negative, it is non-flammable.
