Any other information on results incl. tables

Mixture cellulose/test item:

Mixture	Time (s)	Type of combustion
10 % test item 90 % cellulose	170	Ignition, orange flame
30 % test item 70 % cellulose	170	Ignition, orange flame
50 % test item 50 % cellulose	150	Ignition, orange flame
70 % test item 30 % cellulose	200	Ignition, orange flame
90 % test item 10% cellulose	320	Ignition, orange flame

Mixture cellulose/barium nitrate:

60 % reference item 40% cellulose

300

The pile burns with clear flame without fume.

Applicant's summary and conclusion

Conclusions:

The maximum speed of combustion of barium nitrate/cellulose mixture was lower than all the test
item/cellulose mixtures, therefore the test item has oxidizing properties.
