The term rated capacity or maximum lling level may also be used. 3.3 SAFETY CAN, TYPEIAc a nhaving a short valved spout that may be adapted to both pouring and lling.

25、 3.4 SAFETY CAN, TYPE II A can equipped with a exible or a rigid tubular nozzle attached to a valved spout adapted to pouring only. 3.5 VOLUME, TOTAL The volume equal to the nominal capacity of the can plus any space remaining within the can. CONSTRUCTION 4 Sizes 4.1 The total volume of a can shall

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. The valve shall be capable of being opened manually. 5.4 A can having a nominal capacity of 1

28、.1 quarts (1 L) or less shall not have more than one opening. The opening shall be adapted for pouring and lling. 5.4 revised September 1, 1999 5.5 A can having a nominal capacity of more than 1.1 quarts (1 L) shall not have more than two openings. 5.5 revised September 1, 1999 5.6 Separate pouring

29、and lling valves shall operate independently of each other. 5.7 A spout used for lling, or a separate ll opening, shall be constructed so that the use of a funnel or other article during a lling operation will not interfere with free venting of the can.

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
