National foreword

This British Standard is the UK implementation of EN 13369:2023. It supersedes BS EN 13369:2018, which is withdrawn.

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 committee manager.

EN 13369:2023 and the respective European product standards contain provisions for specific precast products related to design, detailing, tolerances and production which the designer should consider. For products to be used in the UK, matters relating to design should respect decisions made in the UK National Annex to the relevant Eurocode.

Reference is made to “other provisions valid in the place of use”. In the following subclauses, provisions valid in the UK are noted.

4.1.3 – Characteristics of reinforcing steel should be determined in accordance with BS 4449, BS 4483, BS 4482 and BS 8666.
4.1.4 – Characteristics of prestressing steel should be determined in accordance with BS 5896 and BS 4486.
4.2.1.1 – EN 206 is accompanied in the UK by the complementary British Standards BS 8500‑1, Concrete – Complementary British Standard to BS EN 206 – Part 1: Method of specifying and guidance for the specifier and BS 8500‑2, Concrete – Complementary British Standard to BS EN 206 – Part 2: Specification for constituent materials and concrete.

NOTE: EN 206 is referred to in various other clauses; where this occurs, users are encouraged to refer to BS 8500‑1 and/or BS 8500‑2 for details on how EN 206 may be implemented in the UK.

Annex A contains guidance on exposure classes and the minimum concrete cover to reinforcement for precast concrete products. For concrete exposed to environmental conditions in the UK, there is guidance on the quality of concrete and minimum recommended cover for durability, for all conditions, in Annex A of BS 8500‑1:2015+A1:2016, Concrete – Complementary British Standard to BS EN 206 – Part 1: Method of specifying and guidance for the specifier.

For particular applications, the UK committee recommends users refer to the following standards.

For agricultural buildings:

BS 5502‑21:1990, Buildings and structures for agriculture — Part 21: Code of practice for selection and use of construction materials
BS 5502‑22:2003+A1:2013, Buildings and structures for agriculture — Part 22: Code of practice for design, construction and loading

For maritime works:

BS 6349‑1‑4:2021, Maritime works – Part 1-4: General – Code of practice for materials

In informative Annex C, Clauses C.1 to C.4 provide methods to reduce the material safety factors. These are broadly aligned with Annex A of EN 1992‑1‑1:2004+A1:2014, which the UK committee advises takes precedence. In particular where direct structural strength is used when declaring the potential strength (including via Annex B), a reduction in γ_c is included implicitly in the conversion factor η (4.2.2.2.5) and no further reduction in γ_c is recommended (see PD 6687‑1, Background paper to the National Annexes to BS EN 1992‑1, BS EN 1992‑3 and BS EN 1992‑4).

Introduction

This document is intended to outline the general common specifications applicable to a large variety of precast concrete products manufactured in a factory environment. It acts as a reference standard for other standards to enable a more consistent approach to standardization in the field of precast concrete products and to reduce the variations brought about by a large number of standards produced in parallel by different groups of experts. At the same time, it allows those experts the flexibility to include variations in specific product standards where they are required.

This document has been produced as part of the total CEN programme for construction and refers to the relevant specifications of associated standards EN 206 for concrete and the EN 1992 series for the design of concrete structures. The installation of some precast concrete products is dealt with by EN 13670.

As it is not a harmonized standard, it is not allowed to be used on its own for the purpose of CE marking of precast concrete products.

The design of precast concrete products should be verified to ensure the fitness of their properties for the particular application, particular attention being paid to design co-ordination with other parts of the construction.

1 Scope

This document provides the specifications, the basic performance criteria and the Assessment and Verification of Constancy of Performance (AVCP) for unreinforced, reinforced and prestressed precast concrete products made of compact light-, normal- and heavyweight concrete according to EN 206 with no appreciable amount of entrapped air other than entrained air. Concrete containing fibres for other than mechanical properties (steel, polymer or other fibres) is also covered. It does not cover precast reinforced components of lightweight aggregate concrete with open structure nor glass-fibre reinforced concrete.

It can also be used to specify products for which there is no standard. Not all of the specifications (Clause 4) of this document are relevant to all precast concrete products.

Some European product standards refer to this document. They can include specific provisions that take precedence over the provisions of this document.
