Their review confirmed that “the smoke pattern was determined for your wall tests and confirmed a difference between test circumstances and Superb agreement for the tactic for all check conditions” (Riahi 2012). In addition they said that “based on the clean zone place, the flame height plus the fire dimension could be calculated” (Riahi 2012).
