A full-scale fire test, under a positive pressure of 0.2 in. W.G., was carried out on a wall/floor assembly penetrated by a 3-in. ABS DWV pipe. A toilet fixture, mounted on a 3 1/2- in. concrete floor section, was exposed to the furnace and the associated ABS pipe passed through the floor and then through the wall. The section of pipe preceding the wall penetration, although within a fire resistant enclosure, was nevertheless destroyed during the course of the two-hour test. The wall penetration remained intact, however, by virtue of pipe collapse on the unexposed side of the wall.
