Any other information on results incl. tables
Preliminary screening test:
The sample train can be ignited: yes
The combustion propagates along more than 50 mm: yes
The combustion propagates along more than 100 mm: yes
The combustion propagates along 200 mm within: < 4 minutes
Burning rate test must be done: yes
Burning rate test:
| 1. burning rate | 95 s |
| 2. burning rate | 100 s |
| 3. burning rate | 110 s |
| 4. burning rate | 93 s |
| 5. burning rate | 95 s |
| 6. burning rate | 100 s |
Moisture content of the sample: < 0.1 wt.%
Applicant's summary and conclusion
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- The shortest burning rate was determined to be 93 s. The individual results were 95, 100, 110, 93, 95 and 100 seconds.
- Executive summary:
4 -tert-Butylphenol was tested according EU method A10 "Flammability (solids)" 31.05.2008. The preliminary screening test showed that the test substance propagates burning of a 200 mm length of the powder train in less than 4 minutes, therefore a burning rate test was conducted. 4 -tert-Butylphenol was judged to be "non-flammable" as the shortest burning time in up to 6 tests was more than 45 s.
