Internal fire spread – Linings Performance

It is the view of the Department that the requirements of regulation 34 in Part E will be met if the spread of flame over the internal linings of a building is restricted by making provision for them to have low rates of surface spread of flame, and in some cases to have a low rate of heat release, so as to limit the contribution that the fabric of the building makes to fire growth. In relation to the European fire tests and classification system, the requirements of regulation 34 in Part E will be met if the heat released from the internal linings is restricted by making provision for them to have a resistance to ignition and a rate of fire growth which are reasonable in the circumstances. The extent to which this is necessary is dependent on the location of the linings.
