European foreword
This document (FprCEN/TS 1852-2:2025) 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 Vote on TS.
This document will supersede CEN/TS 1852-2:2019.
The main change compared to the previous edition concerns the normative reference to
EN 1852-1:2018+A1:2022.
EN 1852 consists of the following parts, under the general title Plastics piping systems for non-pressure
underground drainage and sewerage — Polypropylene (PP)
— Part 1: Specifications for pipes, fittings and the system
— Part 2: Guidance for the assessment of conformity (the present TS)
Introduction
Figures 1 and 2 are intended to provide general information on the concept of testing and organization
of those tests used for the purpose of the assessment of conformity. For each type of test, 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 as well as the frequency and sampling of testing.
A typical scheme for the assessment of conformity of materials, pipes, fittings, joints or assemblies by
manufacturers is given in Figure 1.

Figure 1 — Typical scheme for the assessment of conformity by a manufacturer
A typical scheme for the assessment of conformity of materials, pipes, fittings, joints or assemblies by
manufacturers, including certification, is given in Figure 2.
Figure 2 — Typical scheme for the assessment of conformity by a manufacturer, including
certification
1 Scope
This document gives guidance for the assessment of conformity of materials, products, joints and
assemblies in accordance with the applicable part(s) of EN 1852 intended to be included in the
manufacturer’s quality plan as part of the quality management system and for the establishment of
certification procedures.
NOTE 1 The quality management system is expected to conform to or be no less stringent than the relevant
requirements in EN ISO 9001 [1].
NOTE 2 If third-party certification is involved, the certification body is expected be accredited to
EN ISO/IEC 17065 [2] or EN ISO/IEC 17021 (all parts) [3], as applicable.
NOTE 3 In order to help the reader, a basic test matrix is given in Annex A.
In conjunction with EN 1852-1 this document is applicable to solid wall piping systems made of
polypropylene (PP) intended to be used for:
— non-pressure underground drainage and sewerage outside the building structure (application area
code “U”), and
— non-pressure underground drainage and sewerage for both buried in 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”.
