BS 6203:2003

This standard BS 6203:2003 Guide to fire characteristics and fire performance of expanded polystyrene materials (EPS and XPS) used in building applications is classified in these ICS categories:

• 13.220.50 Fire-resistance of building materials and elements

This British Standard provides information on the fire characteristics and performance in fire tests of expanded polystyrene materials for use in building applications. This standard illustrates a number of suitable constructions incorporating expanded polystyrene materials, including moulded and extruded products conforming to BS EN 13164 and BS EN 13165. This guide does not apply to expanded polystyrene materials with densities greater than 100 kg/m³.

This guide draws attention to the unsuitability of some standard fire test methods for certain applications of expanded polystyrene materials in buildings.
