Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 1452-2 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 155, Plastics piping systems and ducting systems, in collaboration with ISO Technical Committee
ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 2, Plastics pipes
and fittings for water supplies, in accordance with the Agreement on technical cooperation between ISO and
CEN (Vienna Agreement).
This first edition cancels and replaces ISO 4422-2:1996 and ISO 2045, which have been technically revised.
ISO 1452 consists of the following parts, under the general title Plastics piping systems for water supply and
for buried and above-ground drainage and sewerage under pressure — Unplasticized poly(vinyl chloride)

Introduction
The System Standard, of which this is Part 2, specifies the requirements for a piping system and its
components made from unplasticized poly(vinyl chloride) (PVC-U). The piping system is intended to be used
for water supply and for buried and above-ground drainage and sewerage under pressure.
In respect of potential adverse effects on the quality of water intended for human consumption, caused by the
products covered by this part of ISO 1452, the following are relevant.
a) This part of ISO 1452 provides no information as to whether or not the products can be used without
restriction.
b) Existing national regulations concerning the use and/or the characteristics of these products remain in
force.
Requirements and test methods for material and components, other than pipes, are specified in ISO 1452-1,
ISO 1452-3 and ISO 1452-4. Characteristics for fitness for purpose (mainly for joints) are established in
ISO 1452-5.
This part of ISO 1452 specifies the characteristics of pipes.

Unplasticized poly(vinyl chloride) (PVC-U) —
Part 2:
Pipes
1 Scope
This part of ISO 1452 specifies the characteristics of solid-wall pipes made from unplasticized poly(vinyl
chloride) (PVC-U) for piping systems intended for water supply and for buried and above-ground drainage and
sewerage under pressure.
It also specifies the test parameters for the test methods referred to in this part of ISO 1452.
In conjunction with ISO 1452-1 and ISO 1452-5, it is applicable to extruded PVC-U pipes without a socket and
pipes with a socket (integral or not), intended to be used for the following:
a) water mains and services buried in the ground;
b) conveyance of water above ground for both outside and inside buildings;
c) buried and above-ground drainage and sewerage under pressure.
It is applicable to piping systems intended for the supply of water under pressure up to and including 25 °C
(cold water) intended for human consumption and for general purposes as well as for waste water under
pressure.
This part of ISO 1452 specifies pipes for the conveyance of water and waste water up to and including 45 °C.
For temperatures between 25 °C and 45 °C, Figure A.1 applies.
NOTE 1 The producer and the end-user can come to agreement on the possibilities of use for temperatures above
45 °C on a case-by-case basis.
This part of ISO 1452 specifies a range of pipe sizes and pressure classes, and gives requirements
concerning colours.
NOTE 2 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects,
taking into account their particular requirements and any relevant national regulations and installation practices or codes.

NOTE 1 The tolerance applies to the nominal (minimum) wall thickness and is expressed in the form mm,
0
where x is the value of tolerance for the mean wall thickness, e .
m
[3]
NOTE 2 The tolerance for wall thickness, e, at any point, conforms to grade W of ISO 11922-1 .

6.5 Length of pipe
The nominal pipe length, l, shall be a minimum length which does not include the depth of the socketed
portions, as shown in Figure 1.
NOTE The preferred nominal length of pipe is 6 m. Other lengths are subject to agreement between the
manufacturer and the purchaser.
