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

Results

Preliminary test

The test item did not ignite at room temperature using a flame as ignition source applied for at least 2 minutes. The test item melted.

Main test

In the preliminary test the test item could not be ignited by a flame. Thus the performance of the main test was not necessary.

Final results

The test item did not ignite at room temperature using a flame as ignition source applied for at least 2 minutes. The test item melted.

The product has to be classified neither as a highly flammable solid according to Directive 67/548/EEC, nor as a readily combustible solid in class 4.1 according to the UN Transport Regulation and nor as flammable solid according to GHS / CLP Regulation EC 1272/2008 Annex 1:2.7.

 

Conclusions:
The test substance is a non-flammable solid as determined by E.U. Method A.10.

Description of key information

non flammable
no pyrophoricity
no flammability on contact with water

not self-heating

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

The test substance was determined to be non-flammable according to E.U. Method A.10.

Based on the chemical structure and experience in handling and use, pyrophoricity and flammability on contact with water are not expected.

The substance is completely molten at a temperature well below 160 °C and therefore shows not self-heating behaviour if it is not absorbed on a large surface.

Justification for classification or non-classification

The available data on flammability on ignition, flammability in contact with water, pyrophoricity and self-heating of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008, and are therefore conclusive but not sufficient for classification.
