European foreword
This document (CEN/TS 1401-2:2020) 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 shall not be held responsible for identifying any or all such patent rights.
This document supersedes CEN/TS 1401-2:2012.
Compared with CEN/TS 1401-2:2012, the following changes have been made:
— merging of Table 1 and Table 2 to have the new Table 1 “Formulation tolerances”;
— clarification that a lower content of non-virgin material in the formulation which has already been
Type tested and which is fulfilling the agreed specification is not considered as a material change;
— increase of minimum testing frequencies if a non-virgin material is used.
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;

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 categorised 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.

6 Testing and inspection
6.1 Material specification
For the purposes of this document, the material specification consists of a formulation which defines
PVC resin, additives, non-virgin material (if applicable) and their dosage levels.
The dosage level of ingredients of a formulation shall not exceed the tolerances given in Table 1. If any
dosage level exceeds the tolerance or if a type is changed, this variation constitutes a change in material
(it is referred to as “M” in Tables 4 to 6).
In Table 1, the values of the parts X added to 100 parts by mass of PVC shall be specified by the
manufacturer in the quality plan.

means that a lower content of own reprocessed and external reprocessed and/or recycled material in the

considered as a material change.
6.2 Grouping
6.2.1 General
For the purposes of this document, the groups specified in 6.2.2 and 6.2.3 apply.
6.2.2 Size groups
Three size groups are defined for pipes and fittings, as given in Table 2.
For testing purposes, one individual nominal diameter, d , shall be selected from each group.

6.3 Type testing
Relevant TTs shall be carried out whenever there is a change in design or formulation or production
method, (other than routine in-process adjustments), or whenever there is an extension of the product
range.
Type tests, to be carried out when there has been a change of the production site, depend on the extent
of the change. Therefore relevant type tests should be defined individually by the manufacturer.
Type tests shall demonstrate that the products conform to all requirements for the characteristics given
in Table 4 to Table 6, as applicable.

European foreword
This document (FprCEN/TS 1401-2:2019) 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 1401-2:2012.
Compared with CEN/TS 1401-2:2012, the following changes have been made:
— merging of Table 1 and Table 2 to have the new Table 1 “Formulation tolerances”;
— clarification that a lower content of non-virgin material in the formulation which has already been
Type tested and which is fulfilling the agreed specification is not considered as a material change;
— increase of minimum testing frequencies if an non-virgin material is used.
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 by CEN/TC155/WG6 members 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 categorised as non-virgin
material in this document.
Regarding this specific target, some superfluous requirements and inconsistencies existing in the old
version of EN 1401-1 were deleted, and 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

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 be compliant with either
EN ISO/IEC 17065 [2] or EN ISO/IEC 17021-series [3], as applicable.
NOTE 3 In order to help the reader, a basic test matrix is given in Annex A.
In conjunction with EN 1401-1, this document is applicable to piping systems made of unplasticized
poly(vinyl chloride) (PVC-U) intended for non-pressure underground drainage and sewerage:
— buried in ground outside the building structure (application area code “U”);
— both buried in ground within the building structure and outside the building structure (application
area code “UD”).

quality plan (including specifications on joints and assemblies).
NOTE It is expected that the quality management system conforms to or is no less stringent than the relevant

6 Testing and inspection
6.1 Material specification
For the purposes of this document, the material specification consists of a formulation which defines
PVC resin, additives, non-virgin material (if applicable) and their dosage levels.
The dosage level of ingredients of a formulation shall not exceed the tolerances given in Table 1. If any
dosage level exceeds the tolerance or if a type is changed, this variation constitutes a change in material
(it is referred to as “M” in Tables 4 to 6).
In Table 1, the values of the parts X added to 100 parts by mass of PVC shall be specified by the
manufacturer in the quality plan.
