This Part of this document specifies a test method for determining the fire resistance of smoke extraction ducts. It is applicable only to smoke extraction ducts that pass through another fire compartment from the fire compartment to be extracted in case of fire. It represents fire exposure of a fully developed fire.This method of test is only applicable to fire resisting ducts that have passed the test for the appropriate period to EN 1366-1 (ducts A and B). For duct A, it is a requirement for fire resisting smoke extraction ducts that the document under pressure of 300 Pa, as given in EN 1366-1 is increased to 500 Pa when testing to EN 1366-1.
