Overview

CEN/TS 12201-7:2014 - "Plastics piping systems for water supply, and for drainage and sewerage under pressure - Polyethylene (PE) - Part 7: Guidance for the assessment of conformity" - provides manufacturer-focused guidance on how to assess and demonstrate conformity of PE compounds, pipes, fittings, valves, joints and assemblies to the EN 12201 suite. It covers conformity assessment as part of a manufacturer’s quality plan and supports establishment of certification procedures for PE piping systems used in water supply and pressurised drainage/sewerage applications.

Key topics and requirements

• Scope & conditions: Applies to PE piping systems intended for use at a reference temperature of 20 °C and allowable operating pressures (PFA) up to 25 bar. Applicable installation environments include buried pipelines, sea outfalls, in-water laying, and above-ground (including bridge-suspended) runs. (For constant operating temperatures above 20 °C up to 40 °C see EN 12201-1 Annex A.)
• Conformity framework: Describes the testing and inspection concept used for conformity assessment, including Type Testing (TT), Batch Release Tests (BRT), Process Verification Tests (PVT) and Audit Tests (AT). The specification details which characteristics to assess and addresses sampling and frequency principles.
• Grouping and sampling: Guidance for grouping products (size groups, fitting groups, fitting types) to optimise testing while ensuring representative coverage.
• Documentation: Requirements for maintaining type test results, test records and a technical file to support certification and audit processes.
• Quality management & accreditation: Recommends a quality management system at least as stringent as EN ISO 9001. Where certification is used, certification/inspection bodies are recommended to comply with EN ISO/IEC 17065, EN ISO/IEC 17021 or EN ISO/IEC 17020; testing labs should be compliant with EN ISO/IEC 17025.
• New product types: Reflects updates for co-extruded and peelable-layer pipes and their sampling/testing considerations introduced in the revised EN 12201 parts.

Applications and who uses it

• Manufacturers and fabricators - to prepare quality plans, define internal testing regimes and demonstrate product conformity for PE pipes, fittings and valves.
• Certification and inspection bodies - to structure certification schemes and evaluation procedures aligned with EN 12201.
• Testing laboratories - to implement TT, BRT, PVT and AT methods and sampling strategies for PE systems.
• Specifiers, purchasers and utilities - to understand manufacturer conformity evidence and to select compliant products for water supply, pressure drainage and sewerage systems.
• Regulators and infrastructure owners - to reference conformity guidance when setting acceptance criteria for installations (buried, marine outfalls, in-water, above-ground).

Related standards

• EN 12201-1 through EN 12201-5 (General, Pipes, Fittings, Valves, Fitness for purpose)
• EN ISO 9001 (quality management)
• EN ISO/IEC 17025, 17065, 17021, 17020 (laboratory, certification and inspection competence)

saddles, etc.
Fitting group (C) includes the following fitting types: 45° elbows, 90° elbows, tees, reducers, end caps, etc.
Fitting group (D) includes the following fitting types: Swept bends, segmented bends, segmented tees, etc.
6.2 Type testing
Relevant TTs shall be carried out whenever there is a change in design, in compound or production method,
other than routine in-process adjustments, and/or whenever there is an extension of the product range or
change of production site.
Type tests, to be carried out when occurs a change of the production site, depend on the extent of the
change. Therefore, relevant type tests should be defined individually by the manufacturer.
Type tests shall demonstrate that the products conform to all requirements for the characteristics given in
Tables 3 to 6, as applicable.
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:
a) 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;
b) 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.
