Results and discussion
Any other information on results incl. tables
The substance could be ignited by a flame. The burning times over a distance of 100 mm were 220 and 196 seconds. The fastest calculated burning time over a distance of 200 mm is therefore 392 seconds (approx. 6.5 minutes). As this was significantly longer than 4 minutes, no further tests were performed.
Applicant's summary and conclusion
- Interpretation of results:
- other: not highly flammable
- Conclusions:
- The preliminary screening test according to EU Method A 10 (1984) "Flammability (solids)" of Directive 84/449/EEC was performed and the test substance was found to be not "highly flammable" according to the criteria of the directive.
