The method for rigid or semi-rigid materials or composites

Evaluate BS 476-5 Ignitability testing

• none of the specimen flames for more than 10s after removal of the test flame, and
• Burning of any specimen does not extend to an edge (from the bottom edge 75mm) during the application of the test flame or within the 10s period its removal.
