- Abstract
- Fire endurance tests were made of 13 wood partitions 4 ft square and of four partitions 10 ft high and 16 ft wide. Some of the smaller partitions were of untreated longleaf pine, while the others were made of longleaf pine impregnated with various amounts of monoammonium phosphate up to 17 percent by weight. There were built either of one, two, or three pines of 3/4-in. boards, or of a 1 3/4-in. core with 3/16-in. veneers, giving a total thickness of 2 1/8-in. The large partitions were of the latter design and were made of treated birch. The results of the tests of the small panels are compared with results of fire-tube and flame-penetration tests made on specimens representative of each panel.
