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

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.
