International Fibreboard Casecode This code which is prepared in collaboration with ESBO (The European Solid Board Organisation), contains a methodical presentation of all existing box design styles, a code number being assigned to each design. As a reference document, the code is used world-wide and it has been adopted by the United Nations.
Symbols used in drawings and computer systems.
Case dimensions Unless otherwise specified all dimensions are expressed as internal dimensions in mm as follows: Length (L) x Breadth (B) x Height (H) | Length (L) | = the longer dimension at the opening | | Breadth (B) | = the shorter dimension at the opening | | Height (H) | = the dimension from the top of the opening to the base |
The dimensions L B H are specified in each description of the case construction, for some models the numerical value of B can exceed the numerical value of L. Dimensions should be measured under standard climate conditions, on the flat blank from the centre of crease bearing the thickness of the material in mind. For telescope type boxes the height (h) of the upper part (lid) should be given as a fourth measurement after an oblique stroke, i.e. | 355 | x | 205 | x | 120/40 | mm | | (L) | | (B) | | (H) (h) | | For cases with overlapping outer flaps the length of the area of overlapping (o) should be given as a fourth measurement after an oblique stroke. i.e. | 355 | x | 205 | x | 120/ 40 | mm | | (L) | | (B) | | (H) (o) | |
Sheet dimensions Unless otherwise specified, the dimensions of a corrugated sheet are expressed in mm as follows: - 1st dimension x 2nd dimension
1st dimension=along the glue lines
2nd dimension =across the glue lines
Style versions Several case types may have derived versions without the necessity to create a new style. In this case a suffix should be added to the basic style number separated by a dash. - Example 0201-2.
Aversion maybe unique to individual manufacturers.
Combination of types The construction styles shown are of the basic types of fibreboard cases. If the ultimate construction is a combination of two or three basic models. e.g. flap arrangements, they may also be described as follows: Top flaps as 0204, Bottom flaps as 0215 This type may also be described as 0204/0215 (Top flaps. Bottom flaps). 
Styles and the manufacturers joint The drawing style layouts as shown in this Code may need to be re-arranged depending on the Manufacturers Joint chosen. Some styles may have a Manufacturers Joint which maybe glued, stitched or taped. A glued or stitched Joint may be an extension of either the short or the long panel. The sketches show how these would be indicated on a drawing:  This applies to all designs in this Code.
Manual of Automated erection Each design style includes one of the following indications M - usually manual erection
A - usually automated erection
M/A - can be either manual or automated
M+A - requires a combination of both These indications are based on current practice and are intented to give additional information to specifiers and users Some manually erected cases can be closed automatically (e.g : 0216 or 0712) |
