Abstract

This Part of EN 1366 specifies a method for determining the fire resistance of horizontal 1-, 2- or 3-sided ventilation ducts and ducts whose fire resistance depends on the fire resistance performance of a ceiling or wall (where ducts are located in cavities enclosed by fire-resistant shafts or ceilings). The test examines the behaviour of ducts exposed to fire from the outside (duct A) and fire inside the duct (duct B). This Standard is used in conjunction with EN1363-1. This test method does not take into consideration the effect of spalling or deflection of the adjoining floor/wall. This test method is only applicable to ventilation ducts that have passed the test for the appropriate time period according to EN1366-1 (Duct A and B) in vertical and horizontal orientations. The test specimens should not incorporate access panels, these are tested in accordance with EN1366-1.
