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

Preliminary Test

The test item did not ignite using a flame (min 1000 °C) as ignition source for at least 2 minutes. The test item melted.

Main Test

In the preliminary screening test the test item could not be ignited. Thus, the performance of the main test was not necessary.

Classification

The test item is classified as follows:

UN Transport Regulation:

The test item does not meet the classification criteria as readily combustible solid in Class 4 Division 4.1 according to the UN Transport Regulation.

GHS / CLP Regulation EC 1272/2008 Annex 1:2.7:

The test item does not meet the classification criteria as flammable solid, according to GHS and EC 1272/2008 (CLP Regulation) Annex 1, Section 2.7.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The test item N-[2-(4-oxo-4H-3,1-benzoxazin-2-yl)phenyl]naphthalene-2-sulphonamide could not be ignited in the preliminary screening test by applying a flame (min. 1000 °C) as ignition source for at least 2 minutes.
The test item does not meet the classification criteria as a highly flammable solid nor as a readily combustible solid in class 4.1 according to the UN Transport Regulation. Likewise, classification as a flammable solid is not required according to GHS / CLP Regulation EC 1272/2008 Annex 1, Section 2.7.
