Large-scale reaction-to-fire test

Other Large-Scale Reaction-To-Fire Tests.380... [Pg.350]

Often it is very difficult to determine the burning behavior of complex objects on the basis of the performance of its individual components in bench-scale reaction-to-fire tests. It is much more practical to measure the heat release rate and related properties for the complete object. This requires a large-scale test. In other cases, it is not possible to capture certain aspects of real fire behavior such as melting, delamination, joint effects, etc., in a bench-scale test. A large-scale test is needed to assess these effects. Two commonly used large-scale reaction-to-fire tests are test methods are discussed as follows. [Pg.377]

In some cases, it is not possible to evaluate a material or product (combination of materials) in a bench-scale test in a manner that is representative of its end-use. For example, it is difficult to use a bench-scale test method to evaluate the effect of joints on the fire performance of a thick sandwich panel that consists of a plastic foam core and metal skins. In this case, a room test is used to assess the reaction to fire of the materials. It is also very difficult to assess the fire performance of complex objects such as upholstered furniture based on the reaction-to-hre characteristics of the object s components. Large-scale reaction-to-hre tests have been developed to evaluate these complex objects. [Pg.355]

An appeals procedure and the use of a large-scale room-comer reference test could be invoked in cases where it can be argued that the SBI test might not give a tme reflection of the reaction to fire performance in a given end use. Such appeals can be requested by Member States or industry federations and CEN, the European standards authority. [Pg.119]
