European foreword

This document (EN 1401-1:2019) has been prepared by Technical Committee CEN/TC 155 “Plastics

piping systems and ducting systems”, the secretariat of which is held by NEN.

This European Standard shall be given the status of a national standard, either by publication of an

identical text or by endorsement, at the latest by January 2020, and conflicting national standards shall

be withdrawn at the latest by January 2020.

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 EN 1401-1:2009.

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 categorized 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 formulation and

to the final characteristics and performance of products.
Compared to the previous version, the main changes are listed below:
a) clarification of product covered (Clause 1);
b) introduction of a new pipe series SN 16 (SDR 27,6) (7.2.5 and 7.4.1.2);
c) deletion of former clause on dimension of "o-ring type joints";

d) complete review of non-virgin (recyclates) material use (Clause 5 and Annex A);

e) addition of a footnote e) to Table 14 for DSC to lower the minimum B-onset temperature to 180 °C

for formulation with CaZn stabilizers.

This document 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.

1 Scope

This document specifies the requirements for solid wall pipes with smooth internal and external

surfaces, extruded from the same formulation throughout the wall, fittings and the system of

unplasticized poly(vinyl chloride) (PVC-U) piping systems in the field of non-pressure underground

drainage and sewerage:

— buried in ground outside the building structure (application area code "U"), and

— both buried in ground, within the building structure and outside the building (application area code

"UD").
NOTE 1 The intended use is reflected in the marking of products by "U" or "UD".

It also specifies the test parameters for the test methods referred to in this document.

NOTE 2 Multilayer pipes with different formulations throughout the wall and foamed core pipes are covered by

EN 13476-2 [1].

This document covers a range of nominal sizes, a range of pipes and fittings series and a range of

stiffness classes and gives recommendations concerning colours.

NOTE 3 It is the responsibility of the purchaser or specifier to make the appropriate selection from these

aspects, taking into account their particular requirements and any relevant national regulations and installation

practices or codes.

It is applicable to PVC-U pipes and fittings, their joints and to joints with components of other plastics

and non-plastics materials intended for buried piping systems for non-pressure underground drainage

and sewerage.

NOTE 4 Pipes, fittings and other components conforming to any of the plastics product standards listed in

Annex C can be used with pipes and fittings conforming to this document, provided they conform to the

requirements for joint dimensions given in Clause 7 and to the requirements of Table 16.

arithmetical mean of a number of measurements of the inside diameter of a socket in the same cross-

section
3.8
out-of-roundness
ovality

difference between the measured maximum and the measured minimum outside diameter in the same

cross section of a component
3.9
wall thickness

value of measurement of the wall thickness at any point around the circumference of a component

3.10
mean wall thickness

arithmetical mean of a number of measurements of the wall thickness, regularly spaced around the

circumference and in the same cross section of a component, including the measured minimum and the

measured maximum values of the wall thickness in that cross section
3.11
standard dimension ratio
SDR

numerical designation of a pipe series, which is a convenient round number, approximately equal to the

ratio of the nominal outside diameter d of а pipe to its nominal wall thickness e

n n
3.12
ring stiffness class

numerical designation of the ring stiffness of the pipe or fitting which is a convenient round number,

indicating the minimum required ring stiffness of the pipe or stiffness of the fitting

3.13
solid wall pipe

pipe with smooth internal and external surfaces extruded from the same formulation throughout the

wall

Note 1 to entry: Pipes having more than one layer are considered as solid wall pipes, provided they are all made

from the same formulation.
3.14
fabricated fittings

fittings produced from pipe and/or from injection-moulded fittings by thermoforming, adhesive joint or

welding
Note 1 to entry: Fabricated fittings need an additional fabrication step.
3.15
virgin material

material in a form such as granules or powder that has not been subjected to use or processing other

than that required for its manufacture

Note 1 to entry: Virgin material is a material to which no own and/or external reprocessed or recycled material

has been added.

Note 2 to entry: It is understood that the addition of additives such as stabilizers and pigments is still resulting

into a virgin material.
3.16
non-virgin material
all material which is not defined as virgin material

Note 1 to entry: It covers own reprocessed material, external reprocessed materials and recycled materials.

3.16.1
own reprocessed material

material prepared from rejected unused pipes, gutters, fittings and ancillaries, including trimmings

from the production, that will be reprocessed in a manufacturer’s plant after having been previously

processed by the same manufacturer by a process such as moulding or extrusion and for which the

complete formulation is known
3.16.2
external reprocessed material

material prepared from unused thermoplastics products regardless of where those products were

manufactured

Note 1 to entry: External reprocessed material is often called post-industrial recyclate.

3.16.3
recycled material
material prepared from used t
