Applicant's summary and conclusion

Interpretation of results:
other: no oxidising properties
Remarks:
Migrated information
Conclusions:
The maximum burning rate obtained with the test item was:
2.86 mm/s for the test item / cellulose mixture (10/90% and 20/80%).
The maximum burning rate obtained with the reference item was:
3.23 mm/s for the reference item / cellulose mixture (50/50%).
The maximum burning rate of test item / cellulose mixture was slower than the maximum burning rate with reference item / cellulose mixture.
The test item was not considered to have oxidizing properties under our experimental conditions.
