European foreword
This document (FprCEN/TS 1401-2:2025 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 1401-2:2020.
Compared with CEN/TS 1401-2:2020 the following changes have been made:
— Update of normative references to EN 1401-1:2019+A1:2023
EN 1401, Plastics piping systems for non-pressure underground drainage and sewerage — Unplasticized
poly(vinyl chloride) (PVC-U), consists of the following Parts:
— Part 1: Specifications for pipes, fittings and the system;
— Part 2: Guidance for the assessment of conformity.
Introduction
This revision of the EN 1401 series is proposed in order to improve the 'level of sustainability' and the
'environmental impact' of PVC piping systems, whilst improving the recommendations and safe use of
recycled material. Recycled material is categorized as non-virgin material in this document.
Regarding this specific target, more focus was given to the control of applied material formulation and to
the final characteristics and performance of products.
This document is based on the template prepared in CEN/TC 155/WG21 version V.5.
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. This document details the applicable
characteristics to be assessed as well as the frequency and sampling of testing for each type of test, i.e.
type testing (TT), batch release test (BRT), process verification test (PVT) and audit test (AT).
A typical scheme for the assessment of conformity of formulations pipes, fittings, assemblies by
manufacturers is given in Figure 1.

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

1 Scope
This document gives requirements and guidance for the assessment of conformity of formulations,
products and assemblies in accordance with EN 1401-1 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 The quality management system is expected to conform to or is no less stringent than the relevant
requirements to EN ISO 9001 [1].
NOTE 2 If third party certification is involved, the certification body is expected to be compliant with either
EN ISO/IEC 17065 [2] or EN ISO/IEC 17021-series [3], as applicable.
