For hard-to-ignite dusts with low KSt-values, a very strong ignitor may overdrive a 20-L chamber, as discussed in E1515 and Ref 2. If a dust has measurable (nonzero) Pmax- and KSt-values with a 5000 or 10 000-J ignitor but not with a 2500-J ignitor in a 20-L chamber, this may be an overdriven system.
