Results and discussion
Flammable solids
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Burning time:
- 0 s
- 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
- Remarks:
- During flame contact the substance melted, emitted yellow sparks and turned into a dark brown residue. Grey smoke was observed.
Applicant's summary and conclusion
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- The substance is non-flammable
- Executive summary:
The preliminary screening test was performed for the determination of the flammability of the substance. No propagation of combustion of the substance 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 substance is considered ‘not highly flammable’.
