In particular the ultimate tensile and tensile yield strength of steel shall be considered.

For prestressed elements the values of tolerance in lateral bow (0) and angular deviation of ribs (/) can be increased by 50 %; this includes the effect of prestressing tolerances. The differences in camber or sag, with respect to the declared value, shall be not greater than L/500.

NOTE For CE marking see Annex ZA. 8 Technical documentation The detailing of the element, with respect to geometrical data and complementary properties of materials and inserts, shall be given in technical documentation, which includes the construction data, such as the dimensions, the tolerances, the layout of reinforcement, the concrete cover, the surface characteristics (when relevant), the expected transient and final support conditions and lifting conditions. The composition of technical documentation is given in Clause 8 of EN 13369:2004.

Examples of elements Some examples of cross-sections of precast elements considered in this document are shown in Figure A.1. The elements can be simply supported, or connected longitudinally on or with the beams, achieving total or partial continuity. They also can be designed with half joints at the ends, in order to reduce the total thickness. According to the different situations, the elements can be: a) placed on site without transversal connections, eventually supporting secondary elements between them (isolated members); b) provided with steel plates at their lateral edges to be connected together at their top flanges by welded shear connectors; c) shaped in form of shear keys at their lateral edges to be connected together by
cast in situ shear joints, and/or be provided with steel plates for welded connections on site; d) provided with a cast in situ reinforced concrete topping. Such topping, if effectively restrained to the precast elements by bond, with or without steel reinforcement projecting from the elements, may be taken into account in the resistant section. Combinations of the preceding cases are also possible. According to the different arrangement of connections, the elements can be:  able to act as a diaphragm in order to transfer horizontal forces to the bracing elements (cases b, c, d and a if the secondary elements are adequately connected).  able to transfer vertical shear from heavier loaded elements to the surrounding ones (cases c, d and b if the welded connection is arranged in an appropriate way).

Minor floor elements B.1 General In view of their use as specified in B.2.1, minor floor elements may be designed in the lower consequences class of Clause B.3.1 of EN 1990:2002. In this case they shall be in compliance with the additional requirements and special rules of this annex. Design, production and application of Minor Floor Elements, according to these special rules, is only allowed if manufacturing takes place under strict production control.
B.2 Additional requirements for Minor Floor Elements B.2.1 General Minor Floor Elements are ribbed precast floor elements with limited dimensions, used only for a suspended floor with a maximum below air space of 1 000 mm between the floor and the ground, which are in compliance with the additional requirements of paragraph B.2.2 and B.2.3. NOTE According to consequences classes stated in B.3.1 of 1990:2002, taking into account the use stated above, some special design rules are given for these products. Examples of some forms of Minor floor elements are given in Figure B.1.

B.2.2 Dimensions Minor floor elements shall comply with the following dimensions (referred to the concrete-element, without thermal insulation): span of the elements ≤ 8 000 mm height of the elements ≤ 400 mm width of the ribs ≥ 60 mm spacing between ribs ≤ 1 200 mm thickness of the slab:
