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. For the purposes of the test described in this document, the duct is referred to as duct C. This test has been designed to cover both vertical and horizontal smoke extraction ducts. However, provided both horizontal and vertical tests have been carried out to EN 1366-1 on the specific system, a vertical system need not be evaluated to this method provided it has been tested in a horizontal orientation to this method. However, if the system in practice is only to be used for vertical applications in smoke extraction systems, then it will need to be tested in a vertical orientation to this method. This method of test is only suitable for ducts constructed from non-combustible materials (Euroclass A1 and A2). It is applicable only to four sided ducts; one, two and three sided ducts are not covered.
