- Burning time:
- > 4 min
- Remarks on result:
- other:
- Remarks:
- No propagation of combustion of the test item along 200 mm length of the pile within 4 minutes was observed. According to the guidelines, performance of the burning rate test is not required.
Any other information on results incl. tables
In contact with the flame of the gas burner the test item melted and turned into off white/ light brown residue. Grey smoke was observed. After removal of the ignition source, no propagation of combustion of the test item was observed.
