This European Standard specifies the design and dimensions of the 26 mm screw finish with three thread starts for flat waters and non-carbonated beverages. This finish can be used for aseptic filling and filling with nitrogen charge (internal overpressure inferior to 1 bar max). The dimension (12,0) is the height in millimetres from the top of finish to the bottom of the support ledge. This finish is designed to accept a tamper evident plastic closure only. During first opening, the tamper evident band will separate from the closure shell and remain on a one way bottle neck or like bottles in the returnable market the tamper evident band will tear but will remain connected to the closure shell.
