The plugs shall have a wrenching insert projection we
29、lded to the bottom of the sump of the plug or have a wrenching device formed as part of the plug. The dimensions of the wrenching insert shall be such that the plugs can be operated by a universal tool for steel and plastics plugs. Examples are shown in annex D. NOTE For recommended closing torques,

Capseals/overseals shall be so designed that they can be removed by means of a s
31、imple tool. 5.4 Label rings and protection rings Label rings and/or protection rings shall be designed so that, when fitted, they can be mechanically inserted simultaneously with the flanges. Label rings shall have provisions for customs sealing. NOTE Label rings and/or protection rings can provide
32、adequate reinforcement for the flange insertion and can protect the drum stock neck against corrosion.
