AbstractResults from six ASTM round Robin materials are presented. The tests were performed in accordance with ASTM E1321-90. The six materials are: plywood, FR plywood, polystyrene foam, polyurethane foam, gypsum wallboard, and composite board. The plywood performed predictably in both ignition and flame spread tests. FR plywood exhibited inconsistent behavior in both tests. Polystyrene foam melted and wasaccumulated in the specimen holder before flame attachment commenced. Polyurethane foam gave out volatile combustibles within the first 40 seconds of exposure and formed a char outer layer. These volatile combustibles burned at the pilot flame without any visible flame attachment to the specimen. The gypsum wallboard tests indicated that only the paper cover of the wallboard burned. There was no apparent contribution to either ignition or flame spread from the gypsum core. The composite board, consisting of a particleboard core and thin surface laminations, formed surface blisters. The ruptured blisters led to the exposure of the particle-board core, which later ignited. From this series of tests it can be concluded that the test method is unsuitable for polystyrene and polyurethane foams.
