National foreword

This British Standard is the UK implementation of EN 14844:2006+A2:2011. It supersedes BS EN 14844:2006+A1:2008 which is withdrawn.

The start and finish of text introduced or altered by amendment is indicated in the text by tags. Tags indicating changes to CEN text carry the number of the CEN amendment. For example, text altered by CEN amendment A1 is indicated by .

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.

EN 14844:2007 is a candidate “harmonized” European standard and fully takes into account the requirements of the European Commission mandate M/100, Products related to precast concrete, given under the EU Construction Products Directive (89/106/EEC), and is intended to lead to CE marking. The date of applicability of EN 14844 as a “harmonized” European Standard, i.e. the date after which this standard may be used for CE marking purposes, is subject to an announcement in the Official Journal of the European Communities.

EN 14844 is the subject of transitional arrangements agreed under the Commission mandate. The Member States have agreed a nominal transition period for the co-existence of EN 14844 and their corresponding national standard(s). It is intended that this period will comprise a nominal nine month period, during which any required changes to national regulations are to be made, followed by a further nominal 12 month period for the implementation of CE marking. At the end of this co-existence period, the national standard(s) will be withdrawn. In the UK, there are no corresponding national standards.

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 British Standard was published under the authority of the Standards Policy and Strategy Committee on 29 June 2007

This European Standard was approved by CEN on 17 April 2006 and includes Amendment 1 approved by CEN on 22 August 2008 and Amendment 2 approved by CEN on 22 October 2011.

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-CENELEC 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-CENELEC Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, 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 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 concrete products, from which also the relevant requirements of EN 206‑1, Concrete — Part 1: Specification, performance, 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 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 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 13224, Precast concrete products — Ribbed floor elements
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: Products properties and performances
EN 15037‑1, Precast concrete products — Beam-and-block floor systems — Part 1: Beams
EN 15037‑2, Precast concrete products — Beam-and-block floor systems — Part 2: Concrete blocks
EN 15037‑3, Precast concrete products — Beam-and-block floor systems — Part 3: Clay blocks
EN 15037‑4, Precast concrete products — Beam-and-blocks floor systems — Part 4: Expanded polystyrene locks
prEN 15037‑5, Precast concrete products — Beam-and-block floor systems — Part 5: Lightweight blocks for simple formwork
EN 15050, Precast concrete 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). 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.

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

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, Croatia, 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 Construction Products Directive sets out Essential Requirements to be considered, depending upon the use made of the product. For box culverts it was mandated that the requirements for mechanical resistance and stability should be considered. For these requirements this standard will mainly refer to clauses of EN 1992‑1‑1, Eurocode 2: Design of concrete structures — Part 1-1: General rules and rules for buildings.

The mandate also requires consideration of durability, from the point of view of freeze thaw action and corrosion, which is also addressed by the Eurocodes referred to above.

1 Scope

This European Standard deals with both large (structural) and small (non-structural or light structural) box culverts of rectangular cross-section formed monolithically and designed as continuous elements with a joint detail shaped to allow the possible incorporation of sealing materials. Box culverts can be used for creation of voids below ground for conveyance and storage of materials. e.g. conveyance and storage of wastewater, cable tunnels and subways

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. This standard does not include units manufactured from autoclaved aerated concrete, nor prefabricated reinforced box culverts of lightweight concrete with open structure.

Each unit is structurally complete. They are used in combination to form a total structure of appropriate length (including joints) and capacity.
