The inside body diameter of the canister shall be not less than 6-3/8 inches and not greater than 6-5/8 inches. The outside diameter of the body over the double seam shall not exceed 6-3/4 inches. 3.3 Design and construction:
3.3.1 Body: The body shall be formed from one piece of tinplate not less than 0.015 inch thick. The longitudinal joint shall be an outside or inside lock seam, soldered inside or outside or welded as specified in MIL-C-10464 or PPP-C-96, with a lap seam at each end. The seams shall be soldered the entire length with tin solder. The end ring-to-body seam shall be compound lined. Both ends of the body shall be flanged for lock seaming or crimping of the end rings.
3.3.2 End rings: The end rings shall be formed from tinplate not less than 0.012 inch thick, and shall be not greater than 0.500 inch wide when assembled with the canister body. The end rings shall be flanged for double seaming and shall have an annular groove into which an annular projection on the cover fits. The inside edge of the end ring may be curled under or may project inward to form an additional seal. Flanges shall be precurled and lined with sealing compound conforming to MIL-S-11388.
3.3.3 Cover: The covers shall be formed from tinplate not less than 0.012 inch thick. There shall be an annular projection on the cover to fit snugly into the annular groove in the end ring. When the cover is forced into place on the canister, the cover shall be in continuous contact with the canister on both the outside and the inside of the projection on the cover.
3.3.4 Screens: Both ends of the canister shall be provided with perforated tinplate metal screens, 0.012 inch thick. The total open area of the screens shall be between 25 percent and 45 percent of the total screen area. There shall be at least 17 but not more than 19 holes per inch. The holes shall be 0.033 ± 0.003 inch in diameter. The screens shall be tack soldered to the end rings at three equally spaced locations
