DANSK DSF/PREN 1364-6 PDF

This test method specifies methods for determining the fire resistance of cavity barriers and is to be used in conjunction with EN 1363-1. This document is applicable to non-loadbearing vertically or horizontally oriented closed and open cavity barriers, which are used to provide fire separation to uncompartmented or ventilated spaces. Cavity barriers are designed to provide fire separating performance and the test method is therefore based on the standard room fire exposure in EN 1363-1. Open cavity barrier specimens are installed for test in one of two ways to simulate either normal or sudden exposure to fire in use. Ventilating cavity barriers in facades, where the fire exposure comes as a result of a breaking window and allowing a developed fire to come into contact with the façade, shall be tested as prescribed in Annex D. This document is not applicable to cavity barriers containing penetration seals, which shall be tested to EN 1366-3.
