Foreword
This document (FprCEN/TR 1451-2:2010) has been prepared by Technical Committee CEN/TC 155 “Plastics
piping systems and ducting systems”, the secretariat of which is held by NEN.
This document is currently submitted to the Technical Committee Approval.
This document will supersede ENV 1451-2:2001.
This Technical Report can be used to support elaboration of national third party certification procedures for
products conforming to EN 1451-1:1998.
This Technical Report 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 1451 consists of the following Parts, under the general title Plastics piping systems for soil and waste
discharge (low and high temperature) within the building structure — Polypropylene (PP):
 Part 1: Specifications for pipes, fittings and the system
 Part 2: Guidance for the assessment of conformity (this CEN/TR)

Introduction
Figures 1 and 2 are intended to provide general information on the concept of testing and organisation of
those tests used for the purpose of the assessment of conformity. For each type of tests (i.e. type testing (TT),
batch release test (BRT), process verification test (PVT) and audit test (AT), this document details the
applicable characteristics to be assessed and the frequency and sampling of testing.
A typical scheme for the assessment of conformity of materials, pipes, fittings, valves or assemblies by
manufacturers is given in Figure 1.

A typical scheme for the assessment of conformity of materials, pipes, fittings, valves or assemblies by
manufacturers, including a third-party certification, is given in Figure 2.

1 Scope
This Technical Report gives guidance for the assessment of conformity of materials, products and assemblies
in accordance with the applicable part(s) of EN 1451 intended to be included in the manufacturer’s quality plan
as part of the quality management system and for the establishment of third-party certification procedures.
NOTE 1 It is recommended that the quality management system conforms to or is no less stringent than the relevant
requirements to EN ISO 9001 [1].
NOTE 2 If third-party certification is involved, it is recommended that the certification body is accredited to
EN 45011 [2], EN 45012 [3] or EN ISO/IEC 17021 [4], as applicable.
In conjunction with EN 1451-1 this document is applicable to piping systems made of polypropylene (PP)
intended to be used for:
 inside buildings (marked with "B");
 for both inside buildings and buried in ground within the building structure (marked with "BD").
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

document setting out the specific quality practices, resources and sequence of activities relevant to a
particular product or range of products
3.6
type testing
TT
testing performed to verify that the material, product, joint or assembly is capable of conforming to the
