Overview

CEN/TS 12201-7:2026 - "Plastics piping systems for water supply, and for drains and sewers under pressure - Polyethylene (PE) - Part 7: Assessment of conformity" provides guidance and requirements for assessing conformity of PE compounds, pipes, fittings, joints and assemblies. It is intended to be included in a manufacturer’s quality plan and to support the establishment of certification procedures for PE pressure piping systems used for potable water, raw water, pressure sewers (including vacuum systems), sea outfalls and other non-industrial water applications.

Key topics and requirements

• Scope and applicability: Applies in conjunction with EN 12201‑1 to EN 12201‑5 for PE piping systems (mains and service pipes) used up to 25 bar and a reference temperature of 20 °C. PE100‑RC materials are explicitly included.
• Assessment of conformity (AoC) framework: Defines the organisation of AoC with or without third‑party certification and the roles of manufacturers, laboratories, certification bodies and inspection bodies.
• Testing regimes:
  • Type testing (TT) to demonstrate that materials/products/joints meet standard requirements.
  • Batch release testing (BRT) to permit release of production batches.
  • Process verification testing (PVT) for ongoing confirmation that type test performance is maintained.
  • Audit testing (AT) performed by or for certification bodies to verify continuing conformity.
• Grouping and sampling: Guidance on size groups, fitting groups and fitting types for efficient testing strategies.
• Documentation and records: Requirements for test records, technical files for certification and retention of type test results (valid while no material/product change occurs and PVT is maintained).
• Annexes:
  • Annex A - change of compound and re‑evaluation triggers.
  • Annex B - testing of fabricated fittings.
  • Annex C - informative test matrix (Table C.1) providing an overview of required tests.
• Competence and accreditation: Certification bodies operating to EN ISO/IEC 17065 and inspection bodies to EN ISO/IEC 17020 are considered competent; laboratories to EN ISO/IEC 17025 are referenced. Quality management systems are recommended to meet EN ISO 9001.

Practical applications

• Use this TS to prepare a manufacturer’s quality plan and internal testing schedule for PE water piping products.
• Establish or evaluate certification procedures and audit/testing scope for suppliers.
• Define acceptance criteria and sampling for product release and supplier qualification.
• Inform procurement specifications, compliance checks, and product approval for buried, above‑ground, and special installations (sea outfalls, suspended pipelines).

Who should use this standard

• PE pipe, fitting and valve manufacturers
• Quality and compliance engineers
• Certification and inspection bodies
• Test laboratories
• Asset owners, specifiers and procurers of water and sewer systems

Related standards

• EN 12201‑1 to EN 12201‑5 (system parts)
• EN ISO/IEC 17065, EN ISO/IEC 17020, EN ISO/IEC 17025 (conformity assessment/laboratory competence)

b) a change in design (D);
c) a change of compound (M), see Annex A;
d) a change in production processing method (P), other than routine in-process adjustments;
e) an extension of the product range (E), except the products already covered by the scheme of sampling
procedure.
When a change of production site occurs, the manufacturer shall determine which type tests need to be
revalidated. If certification is involved the scheme should be agreed between the parties concerned.
Unless any of the conditions a) to e) above occurs, the type test results remain valid.
A type test may be performed by the manufacturer or outsourced on behalf of the manufacturer.
A type test can be performed as a witness test if accepted by the certification body.
In case of a change in compound as defined in A.2, relevant type testing requirements as defined in A.3,
and in Tables 3 to 6 as applicable, shall apply.
Effect on water quality shall only be considered for compounds and products intended for the conveyance
of water for human consumption.
For the purposes of a change in design, the following characteristics are relevant:
FprCEN/TS 12201-7:2024 (E)
— dimensions and geometry (see column D1 of Tables 5 and 6), as: change of visual and functional
optimisations, change of overall dimensions, change of a non-PE part;
— joint affected part (see column D2 of Tables 5 and 6), as: change of the dimensions of the fusion zone
(e.g. wire pitch, wire depth), the electrical characteristics (e.g. wire, resistance), the fusion
parameters (e.g. time, voltage).
For the extension of the production range, the relevant characteristics given in Tables 4 to 6, column E,
as applicable, shall be retested. If certification is involved, retesting shall be agreed between the
certification body and the manufacturer.
For fabricated fittings, guidance for type testing is given in Annex B.
