Reaction to fire tests. Spread of flame - Intermediate-scale test of vertical spread of flame with vertically oriented specimen Ingestion-build-100580 Contents of BS EN 1149-5:1 Scope 1. 1 This part of ISO 5658 specifies an intermediate scale method of test for measuring the vertical spread (upward and downward) of flame over a specimen of a product orientated in the vertical position. A measure of lateral spread can also be obtained. It provides data suitable for comparing the performance of materials, composites or assemblies, which are used as the exposed surfaces of walls or other vertically orientated products in
