Any other information on results incl. tables

During the preliminary test the FAT 40840/A TE/cellulose mixture only glowed for about 2 min. The barium nitrate/cellulose mixture during the same test burned for 59 sec with a greenish flame. The burning time of the reaction of the test item mixture was higher than the burning time of the reference mixture; therefore the first step of the main test was performed. For all prepared FAT 40840/A TE/cellulose mixtures only surface burning or no burning was observed and therefore no burning rates could be calculated. Therefore the test was stopped according to the guideline. In comparison: the fastest barium nitrate/cellulose mixture contained 50% barium nitrate.

Conclusions:
FAT 40840/A TE has no oxidizing properties.
Executive summary:

For all prepared FAT 40840/A TE/cellulose mixtures only surface burning or no burning was observed and therefore no burning rates could be calculated. Therefore the test was stopped according to the guideline. In comparison: the fastest barium nitrate/cellulose mixture contained 50% barium nitrate.
