DERMITRON THICKNESS TESTER EQUIPPED WITH SPECIAL PROBE SYSTEM TO MEASURE THICKNESS OF CHROMIUM PLATE IN CALIBER 0.30 GUN BARRELS
Abstract
The purpose of this program was to modify, improve and fabricate a Dermitron gauge for measuring the thickness of chromium in caliber 0.30 gun barrels, based on a prototype developed by the National Bureau of Standards. The NBS prototype gage proved the feasibility of measurements in the 0.30 caliber bore. However a redesign was required in order to make this gage suitable for production inspection conditions. Features of the new design, which represent improvements over the prototype, are described. (Author)
