Results and discussion
Flammable solids
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Burning time:
- 4 min
- 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
Any other information on results incl. tables
Interpretation: If the test item does not propagate combustion along 200 mm of the pile within the 4 minutes test period the test item is considered ‘not highly flammable’.
Results: The flame of the gas burner did ignite the test item pile. The test item glowed, burned with an orange flame, emitted orange sparks and turned into a black residue. Grey smoke was observed. After removal of the ignition source, the flame extinguished after 1 second and no propagation of combustion was observed.
Applicant's summary and conclusion
- Conclusions:
- 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. Based on the results obtained, the test item is considered ‘not highly flammable’.
- Executive summary:
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. Based on the results obtained, the test item isconsidered ‘not highly flammable’.
