Fire Tests of Wood- and Metal-Framed Partitions
The report describes in some detail the test partitions and gives the results of 147 fire-endurance or fire and hose-stream test conducted at the National Bureau of Standards. Seventy-eight of the partitions were of wood or framed with wood studs and faced with wood, wood fiber, or gypsum boards, or with plasters applied on wood, gypsum, expanded-metal, or wire laths. The other were of hollow or solid incombustible nonbearing types, most of which were framed with steel channels and had body or facings of gypsum or portland cement plaster on metal laths. The fire-resistance limit was considered reached when (a) failure under load or passage of flame occurred, (b) the limiting temperature rise (250 degrees F average or 325 degrees F maximum) was reached on the unexposed side, or (c) cotton waste in contact therewith became ignited.
