Abstract : This report describes adaptations of nondestructive testing methods used for detecting defects in protective filter elements. Thermal imaging revealed some flaws in the plasticizer material used for sealing the charcoal impregnated filtration pads and in other areas of the filter. Radiation gauging and X-ray vidicon proved successful for inspecting filters by real-time scanning. These processes obviated the human element and were conducive to assembly-line-type production. Low kilovolt manual X-radiography proved invaluable in refining the other techniques used in this study, all of which hold promise for accelerated inspection. (Author)
