d) changes referring to dangerous substances in Annex ZA. This standard is one of a series of product standards for precast concrete products. For common aspects reference is made to EN 13369 Common rules for precast products, from which also the relevant requirements of the EN 206-1 Concrete — Part 1: Specification, performances, production and conformity are taken. The references to EN 13369 by CEN/TC 229 product standards are intended to make them homogeneous and to avoid repetitions of similar requirements. This standard was examined by and agreed with a joint working group party appointed by the Liaison group CEN/TC 229 – CEN/TC 250, particularly for its compatibility with structural Eurocodes. Eurocodes are taken as a common reference for design aspects. The installation of some structural precast concrete products is dealt with by EN 13670 Execution of concrete structures.
The programme of standards for structural precast concrete products comprises the following standards, in some cases consisting of several parts:  EN 1168, Precast concrete products — Hollow core slabs  EN 12794, Precast concrete products — Foundation piles  EN 12843, Precast concrete products — Masts and poles  EN 13224, Precast concrete products — Ribbed floor elements SIST EN 13225:2013

 EN 14844, Precast concrete products — Box culverts  EN 14991, Precast concrete products — Foundation elements  EN 14992, Precast concrete products — Wall elements  EN 15037, Precast concrete products — Beam-and-block floor systems  EN 15258, Precast concrete products — Retaining wall elements  EN 15050, Precast concrete products — Bridge elements This standard defines in Annex ZA the application methods of CE marking to products designed using the relevant EN Eurocodes (EN 1992-1-1, EN 1992-1-2 and EN 1998-1). Where, in default of applicability conditions of EN Eurocodes to the works of destination, design provisions other than EN Eurocodes are used for mechanical strength and/or fire resistance, the conditions to affix CE marking to the product are described in ZA.3.4. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
This document covers terminology, performance criteria, tolerances, relevant physical properties, test methods, and aspects of transport and erection. This document does not cover load bearing capacity determined by testing.
This standard does not cover lintels with length up to 4,5 m used in masonry walls. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

NOTE In general, the term “product” refers to an element which is produced in large numbers. 3.1 beam element, usually horizontal, for carrying loads primarily by flexure 3.2 column vertical bearing element subject mainly to compression 3.3 frame structure composed of two or more linear elements joined together to ensure stability
4 Requirements 4.1 Material requirements For general aspects, constituent materials of concrete, reinforcing and prestressing steel, inserts and connectors, the relevant clauses of EN 13369:2013, 4.1 shall apply. In particular, the ultimate tensile and tensile yield strength of steel shall be considered. SIST EN 13225:2013

tolerances may be assumed. For the overall positioning of holes and inserts 1,5 times the values of ∆L and ∆h tolerances may be assumed. Other values may be given in project specifications. The values of the tolerances do not include the deformation effects of any applied load or of prestressing. In the verification of the measured deviations, such deformations shall be taken into account by computing their value for the test situation.
NOTE Bow misalignment corresponds to deviation from straightness. For beams in the vertical plane, it corresponds to camber. 4.3.1.1.3 Columns For columns, tolerances of 4.3.1.1.2 are described in Figure 1. SIST EN 13225:2013

National regulations on dangerous substances may require verification and declaration on release, and sometimes content, when construction products covered by this standard are placed on those markets. In the absence of European harmonised test methods, verification and declaration on release/content should be done taking into account national provisions valid in the place of use. NOTE An informative database covering European and national provisions on dangerous substances is available at the Construction web site on EUROPA accessed through: http://ec.europa.eu/enterprise/construction/cpd-ds/ 5 Test methods Clause 5 of EN 13369:2013 shall apply. 6 Evaluation of conformity 6.1 General 6.1 of EN 13369:2013 shall apply.

NOTE For CE marking see Annex ZA. SIST EN 13225:2013

Precautions about lateral buckling of beams Except where proper stiffening and/or bracing provisions are adopted to ensure stability during transitory stages before the completion of the structure, special verifications against lateral buckling should be performed for slender beams for which the horizontal flexural stiffness is much lower than the vertical one. This is the case of narrow sections with Iz << Iy such as the one of Figure A.1. A simplified rule to check the necessity of special verifications is given in 5.9 of EN 1992-1-1:2004.
Figure A.1 — Cross section of a deep beam The different transitory and final situations that may require special buckling verifications are listed below:  lifting conditions with pendulum suspension can be very unstable because of the low degree of restraint and of possible axial compression (see Figures A.2 and A.3);  storage conditions are usually less sensitive to buckling due to the higher degree of restraint, but special care is to be given to ensure the torsional effectiveness of bearings;  transportation conditions of the beams can require a special design, inclusive of possible buckling effects, made case by case;  transitory conditions after installation can submit the beams to overloads while lacking in the bracing effects of the surrounding elements (see Figures A.4 and A.5);  final situation of the completed structure is usually stiffened by the diaphragm effect of the floor or by other special bracing systems, provided lateral supports of the beams and proper connections are applied;  isolated beams in final structural conditions (e.g. for bridge crane railways) require special design calculations, inclusive of lateral and torsional effects of actions, which usually lead to non-slender proportions.

Clauses of this European Standard addressing the provisions of the EU Constructions Products Directive ZA.1 Scope and relevant characteristics This European Standard has been prepared under the mandate M/1001) "Precast Concrete Products" given to CEN by the European Commission and the European Free Trade Association. The clauses of this European Standard shown in this annex meet the requirements of the mandate given under the EU Construction Products Directive (89/106/EEC). Compliance with these clauses confers a presumption of fitness of the linear structural elements covered by this annex for the intended uses indicated herein; reference shall be made to the information accompanying the CE marking. This annex has the same scope as Clause 1 of this standard. It establishes the conditions for CE marking of linear structural elements (such as columns, beams and frame elements) made of reinforced or prestressed normal weight concrete, used for the construction of the structures of buildings and other civil engineering works, except bridges, and shows the relevant clauses applicable (see Table ZA.1).
