26、be sufficient to contain the total volume of liquid corresponding to the nominal capacity of the can. 5 General 5.1 The minimum width or diameter of the base of a can shall not be less than 85 percent of the height of the body. 5.2 An opening shall be above the highest intended liquid level. The ope
27、ning shall not be provided with a removable plug or with a stuffing box leading directly into the can. 5.3 Each opening shall have an automatic valve that remains closed with the can placed in any position.

34、mined by ve micrometer readings made at points spaced equally along the edge of the full piece as rolled. Measurements are to be made not less than 3/8 inch (9.5 mm) from a cut edge and not less than 3/4 inch (19.1 mm) from a mill edge. For drawn parts, the measurements are to be made after drawing.
35、 For painted parts, the thickness is to be measured under the paint. 6.4 The bottom surface of a can shall be recessed at least 1/8 inch (3.2 mm) above the bottom perimeter of the sidewall to reduce the likelihood of puncturing or abrading the bottom. 6.5 The bottom edge of a can having a nominal ca
