This document is applicable to non-loadbearing vertically or horizontally oriented open-state cavity barriers, which are designed to close and provide fire separation in the event of fire.
Open-state 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, can be tested to the optional "flame" criteria.
This document is not applicable to cavity barriers containing penetration seals, which are covered by EN 1366-3.
This document is not applicable to closed cavity barriers, which are covered by EN 1366-4.
