Overview

EN 12201-2:2011/FprA1 is a CEN draft amendment to the European standard EN 12201-2:2011 covering polyethylene (PE) pipes for water supply and for drainage and sewerage under pressure. The document is produced by CEN/TC 155 and focuses on technical changes to pipe wall thicknesses and tolerances (subclause 6.3). It updates Table 2 of the parent standard and clarifies dimensional, pressure-rating and tolerance rules for PE pipes DN/OD 16 up to 2500.

Key topics and requirements

• Scope: PE pipes for potable water supply and pressure drainage/sewerage systems (Part 2: Pipes).
• Wall thicknesses: Updated Table 2 provides nominal and minimum/maximum wall thickness ranges for a wide range of nominal diameters (DN/OD 16–2500) across common pipe series (SDR 21, SDR 26, SDR 33, SDR 41 / S 10, S 12.5, S 16, S 20).
• Material / pressure classes: Mapping of material grades to nominal pressures:
  • PE 40: - (no PN values given in this amendment)
  • PE 80: PN 6, PN 5, PN 4, PN 3.2 (depending on SDR)
  • PE 100: PN 8, PN 6, PN 5, PN 4 (depending on SDR)
• Calculation and rounding rules: Calculated wall thickness (e_min) per ISO 4065 is rounded up to nearest standard minimum (2.0, 2.3 or 3.0 mm) to meet some national requirements.
• Tolerances: Dimensional tolerances follow grade V of ISO 11922-1:1997.
• Design basis: PN values are based on a design factor C = 1.25.
• Amendment detail: Corrected wall thickness values (e and e_min) specifically for DN/OD 2250 and 2500 are included.

Applications

• Specification and procurement of PE pressure pipes for municipal water networks, sewer rising mains and pressure drainage systems.
• Manufacturing quality control: ensuring produced pipes meet the updated wall thickness and tolerance criteria.
• Hydraulic and structural design: selecting appropriate SDR/PN combinations for long-term performance.
• Compliance and testing: laboratories and certification bodies use the standard to verify dimensional and pressure-rating conformity.

Who should use this standard

• Pipe manufacturers and extrusion equipment suppliers
• Water utility engineers, designers and asset owners
• Consulting civil/mechanical engineers and specifiers
• Installation contractors, testing laboratories and conformity assessment bodies
• National standards bodies implementing CEN amendments

Related standards

• EN 12201 (other parts covering fittings, joints and system requirements)
• ISO 4065 (pipe dimensions and tolerancing rules)
• ISO 11922-1 (dimensional tolerances for plastic pipes)

Keywords: EN 12201-2, polyethylene pipes, PE pipes, wall thickness, SDR, PN, DN/OD, water supply, sewerage under pressure, ISO 4065, ISO 11922, CEN/TC 155.

This draft amendment is submitted to CEN members for unique acceptance procedure. It has been drawn up by the Technical Committee
CEN/TC 155.
This draft amendment A1, if approved, will modify the European Standard EN 12201-2:2011. If this draft becomes an amendment, CEN
members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for inclusion of this amendment
into the relevant national standard without any alteration.

This draft amendment was established by CEN in three official versions (English, French, German). A version in any other language made
by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has
the same status as the official versions.
