This report presents some results of series tests on fire resisting bulkhead.Three test specimens were tried. They conformed to the regulations in the International Convention on Safety of Life At Sea 1960, that is, with a surface of approximately 50 square feet (or 4.65 square metres) and height of 8 feet (or 2.44 metres), resembling as closely as possible the intended construction.Test specimens were in three types of typical and practical constructions, namely, type I was a steel bulkhead with stiffeners sprayed with asbestos composition (Trade name is Tomlex) on the surface, type II was a steel bulkhead with stiffeners covered with an asbestos board (Trade name, Marineboard) over the surface, and type III was a steel corrugated bulkhead covered with an asbestos board (Trade name, Marineboard) over the surface.Results of tests are as follows: (1) There did not occur any extraordinary deformations in each type. (2) For type I it is needful to reduce ununiformity in applying sprayed asbestos, and to add suitable treatment for insulation arround anchor clips. (3) In type II and III it is necessary to give suitable treatment around fastening screw taps, and to adopt feather joint for asbestos boards.
