Interpretation of results:
GHS criteria not met
Conclusions:
The sample is not an oxidizing solid substance.
Executive summary:

The test showed that the mean burning
times of Tested- mixture Ⅰ and of Ⅱ were
both greater than that of Standard-mixture Ⅰ
Conclusion: the sample is not an oxidizing
solid substance.
