Preliminary Test:

About 21 g of the test substance were used to form a test pile. The test was started by trying to ignite the pile with a gas flame. After a period of 2 minutes trying to ignite the test substance no ignition could be observed. No burning or glowing spreaded over the length of the pile. During the heating the test substance changed the colour from white to black without producing any smoke but with development of sulphurous smelling gas. During heating the test substance melted an a red glowing melt was formed.

Main Test:

The main test was not performed since the test substance could not be ignited in the preliminary test.

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
Since the test item cannot be ignited it is to be classified as "not highly flammable".
Executive summary:

The aim of the study was the determination of the flammability of the test item. The test substance was not ignited by a gas flame.

The test substance melted du ring trying to ignite the pile at one end with a gas flame. It was assumed that the melt consisted of sulphur. Since the test substance could not be ignited, the test substance was classified as "not highly flammable".

Description of key information

The substance is not flammable.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

The test substance was not ignited by a gas flame. The test substance melted during trying to ignite the pile at one end with a gas flame. It was assumed that the melt consisted of sulphur. Since the test substance could not be ignited, the test substance was classified as "not highly flammable".

Justification for classification or non-classification

The test substance could not be ignited.

Therefore the test substance was classified as "not highly flammable".
