Plastics piping systems for non-pressure underground drainage and sewerage - Unplasticized poly(vinyl chloride) (PVC-U) - Part 1: Specifications for pipes, fittings and the system

This document specifies the 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"), and
- both buried in ground, within the building structure and outside the building (application area code "UD").
NOTE 1   The intended use is reflected in the marking of products by "U" or "UD".
It also specifies the test parameters for the test methods referred to in this document.
NOTE 2   Multilayer pipes with different formulations throughout the wall and foamed core pipes are covered by EN 13476-2 [1].
This document covers a range of nominal sizes, a range of pipes and fittings series and a range of stiffness classes and gives recommendations concerning colours.
NOTE 3   It is the responsibility of the purchaser or specifier to make the appropriate selection from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.
It is applicable to PVC U pipes and fittings, their joints and to joints with components of other plastics and non-plastics materials intended to be used for buried piping systems for non-pressure underground drainage and sewerage.
NOTE 4   Pipes, fittings and other components conforming to any of the plastics product standards listed in Annex C can be used with pipes and fittings conforming to this document, provided they conform to the requirements for joint dimensions given in Clause 7 and to the requirements of Table 16.

Overview

EN 1401-1:2019/prA1 - titled "Plastics piping systems for non-pressure underground drainage and sewerage - Unplasticized poly(vinyl chloride) (PVC‑U) - Part 1: Specifications for pipes, fittings and the system" (CEN) specifies requirements for solid-wall PVC‑U pipes, fittings and system components used in non‑pressure underground drainage and sewerage. It covers pipes with smooth internal/external surfaces, fittings, joints and test parameters for buried applications designated by application area codes "U" (outside building) and "UD" (inside and outside building). Products are marked “U” or “UD” to identify intended use.

Key topics and technical requirements

• Material and formulation
  • Minimum PVC content: ≥ 80% by mass for extruded pipes; ≥ 85% for injection‑moulded fittings.
  • Density range: 1 350 kg/m3 ≤ density ≤ 1 600 kg/m3.
  • PVC content may be measured via chlorine content (EN ISO 1158) or by ash‑rest (EN ISO 3451‑5, Method A) when reprocessed/recycled material is used.
• Physical properties and testing
  • Specifies test parameters and references international test methods (amendment A1 updates normative references to EN ISO 1158 and EN ISO 6259‑2).
  • Defines stiffness classes, nominal sizes and acceptable series of pipes/fittings.
• Joints and compatibility
  • Requirements for joint dimensions (see Clause 7) and joint performance (see Table 16).
  • Compatibility note: components conforming to plastics standards in Annex C may be used if joint dimensions and Table 16 requirements are met.
• Scope limitations
  • Multilayer or foamed-core pipes are excluded (covered by EN 13476‑2).
• Purchaser responsibility
  • Specifier must select appropriate nominal size, series, stiffness class and color per local regulations and installation practices.

Applications and who uses this standard

• Typical applications: gravity drainage, stormwater sewers, external and internal buried sewer runs where non‑pressure flow is required.
• Primary users:
  • Manufacturers of PVC‑U pipes, fittings and joint systems
  • Design engineers and specifiers for civil and infrastructure projects
  • Contractors / installers responsible for underground drainage systems
  • Testing laboratories and conformity assessors
  • Procurement officers and regulators ensuring compliance with CEN requirements

Related standards
