scope:

This test method specifies a method for determining the fire resistance of cavity barriers and is to be used in conjunction with EN 1363-1. This standard 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 slow or sudden exposure in use. This standard is not applicable to cavity barriers containing penetration seals, which are to be tested in accordance with EN 1366-3.
