- Abstract
- One carload of wood fiberboard burned in transit and eight carloads burned in a warehouse 15 days after shipment, causing $2,609,000 loss. Tests to determine the susceptibility of wood fiberboard to self-heating revealed that the ambient temperature to cause ignition varied inversely with the size of the specimen, ranging from 603 deg F. for a 1/8-in. cube to 252 deg F. for an octagonal prism 12-in. thich by 12-in high and 228 deg F. for a 222-in. prism. Pronounced self-heating was evident when the surrounding ari was held at 147 deg F.
