Results and discussion

Any other information on results incl. tables

Preliminary Test

The test article was mixed with dried cellulose in the proportion 2 to 1 (w/w) and the mixture was formed into a small cone shaped pile of 3.5 cm (diameter of base) X 2.5 cm (height) by filling, without tamping, a cone-shaped former. The pile was then placed on a cool, non-combustible, non-porous and low heat-conducting base plate.

The ignition source was applied to the cone, but no ignition or other vigorous reaction was observed.

Reference Mixture and Cellulose

The maximum burning rate of the reference material was achieved with barium nitrate mixed with dried cellulose in the proportion 40 to 60 (w/w).

The results are reported in Table 1.

TABLE 1 Test conducted with various mixtures

Barium nitrate / cellulose (% w/w)	Burning time over 200 mm (sec)	Burning rate (mm/sec)
40 / 60	307	0.65
30 / 70	382	0.52

Test article with Cellulose

The test article was mixed with dried cellulose in various ratios and tested as described in the experimental section above. The results of the different mixtures are reported in Table 2.

TABLE 2 Test conducted on the various mixtures

Mixture	Test article / cellulose (% w/w)	Burning time over 200 mm (sec)	Burning rate (mm/sec)
A	10 / 90	burning does not propagate	-
B	20 / 80	burning does not propagate	-
C	30 / 70	burning does not propagate	-
D	40 / 60	burning does not propagate	-
E	50 / 50	burning does not propagate	-
F	60 / 40	burning does not propagate	-
G	70 / 30	burning does not propagate	-
H	80 / 20	burning does not propagate	-
I	90 / 10	burning does not propagate	-

Since burning did not propagate in any of the test article mixtures, no verification of false positive behaviour using kieselguhr or other tests were required.

Applicant's summary and conclusion
