Any other information on results incl. tables

burning level = 6: very quick combustion under flame-ocurrence

speed of combustion: 34.5 s/100 mm (average value)

Applicant's summary and conclusion

Conclusions:
With an average combustion-speed of 34.5 s/100 mm methenamine was determined to be highly flammable (combustion-speed < 45 s/100 mm).
