What is BS EN 1401-1:2019+A1:2023 - Plastics piping systems about?
This mature European standard is the first in a two-part series on solid wall PVC-U piping systems for construction of underground drains and sewers. BS EN 1401-1:2019+A1:2023 specifies PVC-U pipes, fittings and systems for non-pressure buried applications.
Who is BS EN 1401-1:2019+A1:2023 - Plastics piping systems for?
- Manufacturers/suppliers of PVC-U pipes and fittings
- Engineering consultants, designers and architects
- Purchasers of piping systems for underground drains and sewers
What does BS EN 1401-1:2019+A1:2023 - Plastics piping systems cover?
It specifies requirements for solid wall pipes with smooth internal and external surfaces, extruded from the same formulation throughout the wall, fittings and the system of unplasticized poly(vinyl chloride) (PVC-U) piping systems in the field of non-pressure underground drainage and sewerage:
- Buried in ground outside the building structure (application area code “U”)
- Both buried in ground, within the building structure and outside the building (application area code “UD”)
It also specifies the test parameters for the test methods referred to in the document.
BS EN 1401-1:2019+A1:2023 covers a range of nominal sizes, a range of pipes and fittings series and a range of stiffness classes and gives recommendations concerning colours.
It applies to PVC-U pipes and fittings, their joints and to joints with components of other plastics and non-plastics materials intended for buried piping systems for non-pressure underground drainage and sewerage.
Why should you use BS EN 1401-1:2019+A1:2023 - Plastics piping systems?
- It specifies the requirements for PVC-U pipes, fittings and their joints which have a proven performance over many years.
- Annex C provides information on connectivity between pipes and fittings made to this standard and to other ancillaries/fittings that are covered by BS 4660 and BS EN 13598-1
- It provides the basis for product certification.
- It is widely used to specify PVC-U piping systems for drains and sewers for housebuilding and utilities projects.
- As of the 2019 version, the standard has improved the sustainability of these plastic piping systems by updating provisions for the use of recyclates.
What’s new about BS EN 1401-1:2019+A1:2023?
This is an amendment to BS EN 1401-1:2019 which updates the normative references, in particular replacing references to the now obsolete BS EN 1905.
