For the purposes of this European Standard, box culverts having internal cross-sectional dimensions (W and H in Figure 1) less than or equal to 1 250 mm are considered as small (non-structural or light structural). All other units are defined as large. The elements are generally manufactured in factories using either normal weight or lightweight concrete and usually require reinforcing steel.

These solid slabs have the same overall cross-section as hollow core slabs, however without hollow cores.
The application of the standard is limited for prestressed elements to a maximum depth of 500 mm and for reinforced elements to a maximum depth of 300 mm.
For both types, the maximum width without transverse reinforcement is limited to 1 200 mm and with transverse reinforcement to 2 400 mm.
The elements may be used in composite action with an in situ structural topping cast on site.
