This Technical Specification (CEN/TS) was approved by CEN on 4 October 2002 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia,

Foreword
This Technical Specification (CEN/TS 12666-2:2005) has been prepared by CEN /TC 155, "Plastics piping systems
and ducting systems", the secretariat of which is held by NEN.
This Technical Specification can be used to support elaboration of national third party certification procedures for
products conforming to EN 12666-1:2005.
This Technical Specification (TS) is a Part of a System Standard for plastics piping systems of a particular material
for a specified application. There are a number of such System Standards.
System Standards are based on the results of the work undertaken in ISO/TC 138 "Plastics pipes, fittings and
valves for the transport of fluids", which is a Technical Committee of the International Organization for
Standardization (ISO).
They are supported by separate standards on test methods to which references are made throughout the System
Standard.
The System Standards are consistent with general standards on functional requirements and on recommended
practice for installation.
EN 12666 consists of the following Parts, under the general title Plastics piping systems for non-pressure
underground drainage and sewerage — Polyethylene (PE)
— Part 1: Specifications for pipes, fittings and the system
— Part 2: Guidance for assessment of conformity (the present TS)
— Part 3: Guidance for installation (TS under preparation)
This document includes a Bibliography.
1 Scope
This Part of EN 12666 gives guidance for the assessment of conformity to be included in the manufacturer's quality
plan as part of the quality system.
This Technical Specification includes:
a) requirements for materials, components, joints and assemblies given in EN 12666-1;
b) requirements for the manufacturer's quality system;
[1]
NOTE 1 It is recommended that the quality system conforms to EN ISO 9001:2000 .
c) definitions and procedures to be applied if third party certification is involved.
[2]
NOTE 2 If third party certification is involved, it is recommended that the certification body is accredited to EN 45011 or
[3]
EN 45012 , as applicable.
It is applicable to piping systems made of polyethylene (PE) in the field of non-pressure underground drainage and
sewerage outside the building structure (application area code "U") and for non-pressure underground drainage
and sewerage for both buried in the ground within the building structure (application area code "D") and outside the
building structure. This is reflected in the marking of products by "U"and "UD".
2 Normative references

only the edition cited applies. For undated references, the latest edition of the referenced document (including any
amendments) applies.
