prEN 1366-15 'Fire resistance tests for service installations - Part 15: 1-, 2-, 3- sided ducts
Organization: | CEN |

Page Count: | 36 |
ICS Code (Fire-resistance of building materials and elements): | 13.220.50 |
scope:
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 document is used in conjunction with EN 1363-1.
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 EN 1366-1 (Duct A and B) in vertical and horizontal orientations.
Access panels as part of the duct, if any, are part of the test in accordance with EN 1366-1.
