       Bending- In the term 'proper bending qualities,' the containerboard must be capable of bending along creases or score lines in forming the box so that the containerboard is not ruptured to a point where it seriously weakens the box.
       Box- (also see 'Fibre Box')-A rigid container having closed faces and completely enclosing the contents. When the term 'in boxes' is used in the Classification it signifies that if fibreboard boxes are used, such fibreboard boxes must comply with all requirements of Item 222.
       Box Manufacturers' Certificate (BMC)- A circular or rectangular border printed on fibreboard boxes certifying that all applicable construction requirements of Item 222 have been complied with, containing box manufacturers' name and location for identification purposes.
       Bursting Strength- The strength of material in pounds per square inch as measured by the Mullen Tester.
       Carton- A folding box used as an inner container made from boxboard. Cartons are not recognized as shipping containers.
       Container- A term associated with the outside 'shipping container,' oftentimes designating a fibreboard box not complying with Item 222 and the term 'in boxes.'
       Corrugated Board- A structure formed from two or more paperboard facings and one or more corrugated mediums used in making corrugated fibreboard boxes (see 'Singlewall,' 'Doublewall,' 'Triplewall').
       Corrugating Medium- Paperboard used in forming the fluted portion of the corrugated board which is adhered to the outside facings.
       Corrugation- see 'Flute.'
       Die-cut- The stamped form or process of shaping, cutting, blanking or perforating fibreboard by a die-cutting operation.
       Design style- A style of fibreboard trays or caps having flaps scored, folded and secured at flange sidewalls forming the depth, as opposed to a slotted style having a set of major and minor closing flaps.
       Dimensions:
          Length-The larger of the two dimensions of the open face.
          Width-The lesser of the two dimensions of the open face.
          Depth-The distance between the innermost surfaces of the box measured perpendicular to the length and width.
       Doublewall- The structure formed by three flat facings and two intermediate corrugated mediums.
       Edge Crush Test (ECT)- A test conducted upon a sample of corrugated fibreboard in its vertical position with flutes oriented in the direction of loading to determine its resistance to compression measured as pounds per inch of width. (Also referred to as the Short Column Test).
       Facings- (Sometimes erroneously called 'liners')-A form of linerboard used as the flat members of corrugated fibreboard.
       Fibre or Fibreboard Box- A shipping container made of either corrugated or solid fibreboard having a minimum of six faces and completely enclosing its contents. For classification purposes, when the term 'box' is used, the structure must comply with all requirements of Item 222.
       Flute or Corrugation- One of the waveshapes formed in the corrugating medium. (Sized by: Approximately A = 33 flutes/ft., B = 47 flutes/ft., C = 39 flutes/ft., and E = 90 flutes/ft.).
       Glued (firmly)- Firm gluing is indicated when mutilation of the surface fibres accompanies separation of joined areas after drying.
       ISTA (International Safe Transit Association)- A non-profit organization which establishes laboratory performance test procedures and certifies laboratories to conduct these test procedures.
       Liner (Sleeve)- A creased fibreboard sheet inserted in a container and covering all sidewalls.
       Manufacturers' Joint- The 'joint' is that part of the box where the ends of the sheet are joined together by taping, stitching or gluing and is normally oriented as a vertical corner of a box.
       Medium- see 'Corrugating Medium.'
       Mullen Test- see 'Bursting Strength.'
       Package- (When referring to fibre container)-A container not necessarily complying with the requirements of Item 222 for a 'box.' (See Sec. 5, Item 680.) Also, one of the special authorized containers described in detail in the Classification in the section titled 'Specifications for Numbered Packages,' established as an exception to a general packaging rule.
       Pad (Slip Sheet)- A corrugated or solid fibreboard sheet or other authorized material used for extra protection or for separating tiers or layers of articles when packed or palletized for shipment.
       Partitions- A set of corrugated or solid fibreboard pieces slotted so they interlock when assembled to form a number of cells into which articles may be placed for shipment.
       Ply- Any of the several layers of solid fibreboard.
       Puncture Test- The strength of material expressed in inch ounces per inch of tear as measured by the Beach puncture tester (See Item 222, Sec. 3, Notes 2 and 3).
       Score Line- A crease or a line of compressed fibreboard to facilitate bending or folding.
       Seam- The junction created by any free edge of a container flap or wall where it abuts or overlaps on another portion of the container and to which it may be fastened by tape, stitches or adhesive in the process of closing the container.
       Shell- A sheet of corrugated or solid fibreboard scored and folded to form a joined or unjoined tube open at both ends.
       Singleface- Corrugated fibreboard constructed having a flat single facing adhered to a corrugated medium.
       Singlewall- The structure formed by one corrugated inner medium glued between two flat facings.
       Sleeve- see 'Liner.'
       Solid Fibreboard- A solid board made by laminating two or more plies of containerboard.
       TAPPI (Technical Association of the Pulp and Paper Industry)- A technical society which develops and disseminates knowledge on the technology of pulp, paper and paperboard.
       Triplewall- The structure formed by four flat facings and three intermediate corrugated mediums.
       United Inches- The summation of the outer dimensions of a fibreboard box, length, width and depth added.
       Water Resistant- A board, to be water resistant, shall be sized (treated with water repellant materials) or so calendared so as to have a degree of resistance to damage or deterioration by water in liquid form.
       Weight of Facings- (Minimum combined, of corrugated board)-This is the summation of weight per thousand square feet of all facings in the board structure excluding the weight of coatings and impregnants and excluding the weight of the corrugating medium and the adhesive.
