ON OF HATERIALS:materials used in the test assembly are described below.Column — The column used in the test assembly was a W14X228steel section measuring 8 ft, 3 in. long between the top andThebottom concrete caps.Primer — The pr imer was a corrosionpr imer manufactur ed by TSI, Inc.-inhibiting modified alkydglass fiber gauze wasThe gauzereinforcement.mastic coating to provideGlass Fiber GauzeThewide and weighed 1.70 oz per sq yd.embeddedwas 12.in thein.Mastic Sublimin Coatin — The mastic subliming coatingmaterial was manufactured by TSI, Inc. (and designated Thermo LagType 330, The coating material was supplied in 55 gal steeldrums. The mastic coating is*presently Classified by Under wr itersLaboratories Inc. under Follow-Up Service. The composition andother properties of the mastic coating are considered proprietaryand are on file at the Laborator ies.PROTECTION OF TEST ASSEMBLY:protected by workmen in the employ ofthe submittor under the obser vation of members of theLabor atorThe column surfaces were wiped with a solvent to removeThe primer was sprayed onto the columnsurface contaminates.using an air gun.The mastic coating, which wa's supplied in steel drums, was.spray-applied to the column surfaces using. equipment designed forThesteel columnies'taff.such purposes.was

These varied in width from hairline to 1/16 in. andwereto 2 in. long.1METHODThe column was placed in the furnace and exposed to flames ofcontrolled extent and severity in accordance with the StandardTime-Temperature Curve. Eight thermocouples, distributed aroundthe column in two levels as shown on ILL. 3, measured thetemperatures in the furance chamber.The temper atur es of the steel column were measur ed by 14ther mocouples located as shown on ILL. 4. Thr oughout the test,obser vations wr e made to note the character of the fire, thecondition of the exposed sur face of the column, .and all other datapertinent to the fire resistance performance of the column.Character and Distribution of the Fire - The furnace fire wasluminous and well distributed during the test, and thetemperatures recorded in the furance chamber followed the StandardTime-Temperature Curve as defined in the Standard for Fire Testsof Building Construction and Materials, UL263, and as shown onILL. 3.
