National foreword

This British Standard is the UK implementation of EN 15258:2008.

The UK participation in its preparation was entrusted to Technical Committee B/524, Precast concrete products.

A list of organizations represented on this committee can be obtained on request to its secretary.

This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.

Compliance with a British Standard cannot confer immunity from legal obligations.

This European Standard was approved by CEN on 25 July 2008.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN Management Centre or to any CEN member.

This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the CEN Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

Foreword

This document (EN 15258:2008) has been prepared by Technical Committee CEN/TC 229 “Precast concrete products”, the secretariat of which is held by AFNOR, and was examined by and agreed with a joint working party appointed by the Liaison Group CEN/TC 229-CEN/TC 250, particularly for its compatibility with structural Eurocodes.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2009, and conflicting national standards shall be withdrawn at the latest by July 2010.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.

This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EC Directive(s).

For relationship with EC Directive(s), see informative Annex ZA, which is an integral part of this document.

This standard is one of a series of product standards for precast concrete products.

For common aspects reference is made to EN 13369:2004: 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 13369:2004 by CEN/TC 229 product standards are intended to make them homogeneous and to avoid repetitions of similar requirements.

Eurocodes are taken as a common reference for design aspects. The installation of some structural precast concrete products is dealt with by ENV 13670‑1, Execution of concrete structures — Part 1: Common rules, which has at the moment the status of an European prestandard. In all countries it can be accompanied by alternatives for national application and it shall not be treated as a European standard.

The programme of standards for structural precast concrete products comprises the following standards, in some cases consisting on 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
EN 13225, Precast concrete products — Linear structural elements
EN 13693, Precast concrete products — Special roof elements
EN 13747, Precast concrete products — Floor plates for floor systems
EN 13978‑1, Precast concrete products — Precast concrete garages — Part 1: Requirements for reinforced garages monolithic or consisting of single sections with room dimensions
EN 14843, Precast concrete products — Stairs
EN 14844, Precast concrete products — Box culverts
EN 14991, Precast concrete products — Foundation elements
EN 14992, Precast concrete products — Wall elements
EN 15037‑1, Precast concrete products — Beam-and-block floor systems — Part 1: Beams
prEN 15037‑2, Precast concrete products — Beam-and-block floor systems — Part 2: Concrete blocks
prEN 15037‑3, Precast concrete products — Beam-and-block floor systems — Part 3: Clay blocks
prEN 15037‑4, Precast concrete products — Beam-and-block floor systems — Part 4: Polystyrene blocks
prEN 15037‑5, Precast concrete products — Beam-and-block floor systems — Part 5: Lightweight blocks
EN 15050, Precast concrete products — Bridge elements
EN 15258, Precast concrete products — Retaining wall elements

This standard defines in Annex ZA the application methods of CE marking to products designed using the relevant EN Eurocodes (EN 1992‑1‑1:2004 and EN 1992‑1‑2:2004). 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, the conditions to affix CE marking to the product are described in ZA.3.4 and Z.A 3.5.

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

Introduction

The evaluation of conformity given in this standard refers to the precast elements which are supplied to the market and covers all the production operations carried out in the factory.

For design rules reference is made to EN 1992‑1‑1:2004. Additional complementary rules are provided where necessary.

1 Scope

This European Standard deals with the requirements, the basic performance criteria and evaluation of conformity for precast elements made of plain, reinforced or prestressed normal weight concrete, used for the construction of retaining walls.

The products covered by this European Standard are intended to be used as part of retaining walls in applications such as:

to retain natural ground excavations and trenches;
to retain earth fills for roads, platforms, etc.;
in bridge abutments and their flank walls;
to retain several kinds of loose materials such as sand, gravel, etc.

Some examples of precast elements considered in this European Standard are shown in the Informative Annex B.

The products may be used in seismic areas on condition that they fulfil the requirements specific to this use.

This European Standard does not cover:

products for retaining walls of tanks or reservoirs of liquids;
retaining wall elements up to a height of 1,0 m and those assembled to form retaining walls of up to 1,0 m in height (e.g. stacked flower boxes for dwarf walls) if the corresponding retaining wall is used for secondary loads (max. horizontal earth fill and with light surcharge);
products for stacked planting boxes, having only façade functions, and therefore not submitted to any loads (such as earth pressure loads, highway load effects, etc.);
precast diaphragm walls (concrete sheet piling).
