Il futuro
38
ORA
� Nella preparazione delle EN 45545 la valutazione della tossicità si fa con l’indice CIT
� CIT - Conventional Index of Toxicity� Il quale tiene conto delle concentrazioni di
gas narcotizzanti ed irritanti a 4 minuti e 8 minuti
39
In futuro
� Nel prossimo futuro, il WG dovrebbe adottare la filosofia di Transfeu� Misura dei fumi e gas tossici in continuo per tutta
la durata del test� Calcolo del FED e FEC e determinazione del
tempo in cui si raggiunge la soglia di tenibilità
