Design & Technical Guidance – Quality & Standards
Concrete pipes have been in use for well over 150 years. That long history of proven performance has combined with continuous product development and improvement. Concrete pipes have grown in consistency, performance and efficiency. Product manufacturing technologies have advanced, concrete mixes have improved, jointing seals have become more watertight and durable, new laying and installation methodologies have been introduced and the serviceability of the products have increased. The first British Standard for concrete pipeline products was published in 1927. The current European standard for concrete pipeline products was published in 2002. With this standard concrete drainage products became one of the first construction products to be manufactured to a complete and consistent family of European and British standards.
Demanding standards ensure high performance systems. Concrete pipeline product standards were designed to ensure that products are made to meet the highest performance requirements. They include rigorous product testing on each requirement at every stage of manufacture.
These standards include:
- BS EN 1916 and 1917: These provide information relating to essential performance requirements on material and product characteristics, product strength and testing, watertightness testing, and product sampling and inspection.
- Complementary standards BS 5911 Parts 1 and 3 (for pipes, manholes, and cover slabs) cover other aspects, including detailed cement/concrete content information, geometrical characteristics and finishing, sizes and strength class.
- BS 5911 Part 4 covers reinforced and unreinforced inspection chambers and Part 6 with road gullies and gully cover slabs.
