Foreword

The several parts of BS 5911 specify requirements for various types of concrete pipe and ancillary concrete products such as manholes, inspection chambers and road gullies.

BS 5911‑6 has been prepared under the direction of Technical Committee B/505. BS 5911‑6:2004+A1:2010 supersedes BS 5911‑6:2004, which is withdrawn.

The start and finish of text introduced or altered by Amendment No. 1 is indicated in the text by tags . Minor editorial changes are not tagged.

Amendment A1 introduces the following principal changes:

• all references to other standards have been updated;
• Table 2 and Table 3 have been replaced to align with BS 8500.

BS EN 1916:2002 covers unreinforced, steel fibre and reinforced concrete pipes and fittings with flexible joints and BS EN 1917:2002 covers manholes and inspection chambers manufactured from the same types of precast concrete. Neither contains all the requirements of the existing national specifications of CEN members because complete agreement could not be achieved. Therefore, BS 5911‑1, ‑3 and ‑4 contain requirements from former national British Standards that could not be agreed upon for inclusion in EN 1916 and EN 1917.

Precast concrete road gullies and gully cover slabs are two of the ancillary products often made by manufacturers of concrete pipes and so for over 50 years they have been specified within the same British Standard. Accordingly, for consistency and convenience, it was appropriate for this revision of BS 5911‑230 to be aligned with BS EN 1916, BS EN 1917 and BS 5911‑1, ‑3 and ‑4 wherever practicable.

The requirements for cementitious content and cement groupings have been aligned with the provisions of BS 8500‑1:2006 and BRE Special Digest 1 [1] insofar as they relate to precast concrete pipeline systems.

For an enquiry or order to be fully understood it is essential that the manufacturer be given the information set out in Annex A of this part of BS 5911.

Product certification. Users of this part of BS 5911 are advised to consider the desirability of third party certification of product conformity with this British Standard, based on the conformity attestation arrangements described herein. Users seeking assistance in identifying appropriate conformity assessment bodies or schemes may ask BSI to forward their enquiries to the relevant association.

BSI Committee B/505, whose constitution is shown in this British Standard, takes collective responsibility for its preparation under the authority of the Standards Policy and Strategy Committee. The committee wishes to acknowledge the contribution of the following organizations:

— The British Precast Concrete Federation;
— The Concrete Society;
— The County Surveyors’ Society;
— The Highways Agency.

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.
