Abstract : The ARTC-W-84 panel of the Aircraft Industries Association has adopted a program to standardize test procedures for both conventional and high temperature sealants. Convair was given as an assignment in the progra the investigation of the thermal rupture properties of high temperature sealants and the determination of the effects of fuel immersion on the tensile strength and elongation of conventional sealants. The best rupture test for high temperature sealants is as follows: a 10 psi pressure is applied to a thermal rupture specimen o 1/4 inch hole size in an oven at 275 F for a maximum time of one hour. At the end of that period, the protrusion of the sealant above the level of the panel shall not exceed 1/8 inch. Fuel immersion tests on top-coated tensile-elongation specimens of conventional sealants are feasible. The most suitable fuel immersion period for EC-801 and similar sealants is 7 days. (Author)
