Fire resistance tests for service installations - Ventilation ducts1 Scope This European Standard specifies a method for determining the fire resistance of vertical and horizontal ventilation ducts including those access panels, which are integral part of the tested ducts. The test examines the behaviour of ducts exposed to fire from the outside (duct A) and fire inside the duct (duct B). This European Standard is used in conjunction with EN 13631. Annex A provides general guidance and gives background information.

characterization and quantification of the ceramic granule properties are important steps for improving the production process and properties of the granules for further processing

1 Material condition

These tests are conducted in laboratories using specific test agents under specified conditions and therefore do not indicate the performance of the device in actual use

construction and workmanship

Help organizations improve performance
