Fire tests on building materials and structures - Classification and method of test for external fire exposure to roofs Ingestion-build-209418 The delivery of high-quality componentsThe tests described in this part of BS 476 are designed to give information about fires spreading to the roof of a building from a nearby fire outside the building itself. The tests are not concerned with the behaviour of a roof when subjected to the effects of fire on its underside.
