Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- GLP compliance:
- yes
- Specific details on test material used for the study:
- The batch of Disperse Brown 27 (4852-1501) tested was a brown powder with a purity of 99.7 %
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Burning time:
- ca. 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
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- The test item melted, burned with a yellow flame, emitted sparks and turned into a black residue. Brown smoke was observed. After removal of the ignition source, the flame extinguished after 2 seconds and no propagation of combustion was observed. Test item deemed not highly flammable
- Executive summary:
The test item melted, burned with a yellow flame, emitted sparks and turned into a black residue. Brown smoke was observed. After removal of the ignition source, the flame extinguished after 2 seconds and no propagation of combustion was observed. 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.Test item deemed not highly flammable
