3 Dimensions NOTE 1 Dimensions of fibreboard may vary with variation in moisture content of the material. Accurate measurements of dimensions should therefore be performed under standard climatic conditions (Condition 50 % r.h./23 °C of EN ISO 2233). NOTE 2 The external dimensions should be taken into consideration when using pallets or containers for distribution. NOTE 3 The difference between the external and internal dimensions of the case depends on the thickness of the board and the number of plies present. 3.1 Case dimensions Unless otherwise specified, the dimensions of the erected assembled case are expressed as internal dimensions in mm, and in the following order: L B H. The dimensions L, B and H are specified in each description of the case construction but refer normally to: L (Length) = the longer dimension at the opening B (Breadth) = the shorter dimension at the opening H (Height) = the dimension from the top of the opening to the base NOTE Dimensions should be measured on the flat blank from the centre of the creases taking into account the thickness of the material as appropriate. 3.2 Telescope type cases For telescope-type cases the height (h) of the upper part (lid) should be given as a fourth measurement after an oblique stroke, e.g. 355 205 1 20/40 mm (L) (B) (H)/ (h) 3.3 Cases with overlapping outer flaps For cases with overlapping outer flaps the length of the overlap (o) should be given as a fourth measurement, e.g. 355 205 1 20/40 mm (L) (B) (H)/ (o) 3.4 Sheet dimensions NOTE Unless otherwise specified, the dimensions of a corrugated board sheet are expressed in mm. 3.4.1 Corrugated board sheet 1 st dimension 2nd dimension = (CD MD) = (across the machine direction) (along the machine direction). 1 st dimension = along the glue lines which is parallel to the flutes (CD) 2nd dimension = across the glue lines which is perpendicular to the flutes (MD). 3.4.2 Solid board sheet 1 st dimension 2nd dimension = (CD MD) 1 st dimension = CD (cross direction) 2nd dimension = MD (machine direction). 3.5 Material thickness 3.5.1 General The thickness of a fibreboard material is needed for calculations of the package dimensions. Corrugated board and solid fibreboard are two types of fibreboard material. 3.5.2 Corrugated board For corrugated board the material thickness is mainly determined by construction factors, i.e. single wall or multi- wall types and by the flute profile(s) used. The thickness of the paper components has only a limited influence on the thickness of the board. For corrugated board there are comparatively homogeneous types of constructions referred to as “flute profiles” or “flute types”. 3.5.3 Solid fibreboard Solid fibreboard is available in many thicknesses. The strength properties for the same thickness can show wide differences due to many circumstances in the production, e.g. the pulp and fibre raw material used, the production machine and production methods. The grades are often referred to by basis weight and type of fibre material used. The board producer can give relevant strength properties related to their particular material. 4 Basic type groups 4.1 General The design of corrugated and solid fibreboard cases can be as variable as the types of articles to be packed but there are certain recognized basic type groups. The purpose of this section is to describe a code which is used to identify the design of corrugated and solid fibreboard cases in order to simplify communication between manufacturers, specifiers, users and other parties involved.EN 14053  pdf download.
