Tato část EN 1366 specifikuje zkušební metodu pro stanovení požární odolnosti potrubí pro odvod kouře, které se použije pouze pro jeden úsek. Při tomto použití je systém odvodu kouře určen pouze pro činnost před celkovým vzplanutím (typicky 600 °C).

Tato metoda zkoušení je vhodná pouze pro potrubí zhotovená z nehořlavých materiálů (třída A1 a A2-s1,d0 podle EN 13501-1).

Platí pouze pro čtyřstranná potrubí a kruhová potrubí. Neplatí pro potrubí s jednou, dvěma nebo třemi stranami. Tato norma platí pouze pro normové velikosti nebo menší velikosti, jak je uvedeno.

Zkušební metoda v této části 9 je určena pouze pro potrubí pro odvod kouře, které neprochází jiným požárním úsekem. Pro potrubí pro odvod kouře, která procházejí jiným požárním úsekem, se použije metoda zkoušení popsaná v EN 1366-8.

Potrubí pro odvod kouře je součástí systému pro odvod kouře, který zahrnuje také klapky pro odvod kouře
