Results and discussion

Flammable solids
Test procedure:
burning rate test over 100 mm length
Burning time:
< 28 s

Any other information on results incl. tables

First two tests were performed after 30 minutes from the preparation of the test pile, they didn't burn until reaching the length of 100 mm probably for the hygrospicity of the material. In the third test the pile extinguished after about 160 mm. In the fourth test the pile deflagrated over a distance of more than 200 mm, the propagation of deflagration proceeded in less than 28 seconds for the 100 mm following the first 80 mm.

Applicant's summary and conclusion

Interpretation of results:
study cannot be used for classification
Conclusions:
The fastest burning time (deflagration time) over a distance of 100 mm for ADN was determined to be less than 28 seconds. According to EEC Directive 92/69, Part A, Methods for the determination of physico-chemical properties, A.10 "Flammability (solids)", EEC Publication No. L383, December 1992 the substance was classified as highly flammable.
