Foreword
This document (CEN/TS 1455-2:2012) has been prepared by Technical Committee CEN/TC 155 “Plastics
piping systems and ducting systems”, the secretariat of which is held by NEN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document supersedes ENV 1455-2:2001.
Compared with ENV 1455-2:2001, the following changes have been made:
a) Use of the template drafted by CEN/TC 155/WG 21 for assessment of conformity documents (change of
"Terms and definitions" and addition of 1 column "Sampling procedures" in Tables);
b) Deletion of all requirements for TPE seals as they are no longer required;
c) Addition of an informative Annex A: Basic test matrix.
EN 1455 Plastics piping systems for soil and waste discharge (low and high temperature) within the building
structure — Acrylonitrile-butadiene-styrene (ABS) consists of the following Parts:
 Part 1: Requirements for pipes, fittings and the system
 Part 2: Guidance for the assessment of conformity (the present TS)
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Croatia, Cyprus,
Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,
Spain, Sweden, Switzerland, Turkey and the United Kingdom.

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 test, i.e. type test (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 (compounds/formulations), pipes, fittings,
joints or assemblies by manufacturers is given in Figure 1.

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

1 Scope
This Technical Specification gives guidance for the assessment of conformity of materials
(compounds/formulations), products and assemblies in accordance with EN 1455-1 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.
NOTE 3 In order to help the reader, a basic test matrix is given in Annex A.
In conjunction with EN 1455-1, this document is applicable to solid-wall piping systems made of acrylonitrile-
butadiene-styrene (ABS) intended to be used for the following purposes:
 for soil and waste discharge (low and high temperature) inside buildings (application area code "B");
 for soil and waste discharge (low and high temperature) inside buildings and buried in ground within the
building structure (application area code "BD").
NOTE 4 This is reflected in the marking of products by "B" or "BD".
