Overview

EN ISO 1452-2:2009 / ISO 1452-2:2009 specifies requirements for solid‑wall pipes manufactured from unplasticized poly(vinyl chloride) (PVC‑U) used in piping systems for water supply and for buried and above‑ground drainage and sewerage under pressure. Prepared by CEN in collaboration with ISO, this part (Part 2: Pipes) covers extruded PVC‑U pipes with or without sockets (integral or separate) and sets test parameters for the referenced test methods.

Key topics and requirements

• Scope and application: Pipes for water mains, service lines buried in the ground, above‑ground conveyance (inside and outside buildings), and buried or above‑ground drainage and sewerage under pressure. Applicable for cold water up to and including 25 °C (potable and general use) and for conveyance up to 45 °C (with guidance for higher temperatures handled case‑by‑case).
• Material and material properties: Requirements for PVC‑U pipe material, including density and MRS (minimum required strength) parameters.
• Geometrical characteristics: Nominal and mean outside diameters, wall thicknesses and tolerances, pipe lengths, and socket geometries.
• Mechanical and physical tests: Impact strength, resistance to internal pressure (reference to ISO 1167‑1), and other physical performance checks. Test parameter values and methods are specified.
• Joints and end preparations: Requirements for pipe ends suitable for ring‑seal or solvent‑cement joints and for pipes with sockets (integral or not).
• Classification and selection: Guidance on pressure classes and pipe series selection for different temperature ranges and service conditions.
• Marking, colours and traceability: Minimum marking requirements, colour guidance and identification for intended use.
• Annexes: Normative annexes include allowable operating pressures and imperial (inch) sizes.

Practical applications and users

EN ISO 1452‑2 is used by:

• Manufacturers of PVC‑U pipes to design, test and mark products to comply with European/ISO requirements.
• Specifiers and engineers selecting pipe sizes, pressure classes and joint types for potable water, irrigation, plumbing and sewerage under pressure.
• Water utilities, contractors and installers executing buried mains, service connections, and above‑ground installations.
• Test laboratories and conformity bodies performing mechanical and pressure tests and verifying compliance.
• Procurement and regulators referencing a harmonized standard for safety, fitness for purpose and interoperability.

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

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.

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.

is expressed in the form mm, where x is the value of the tolerance.
b
The tolerance is expressed as the difference between the largest and the smallest outside diameter in a
cross-section of the pipe (i.e. d − d ).

For d u 250, the tolerance conforms to grade N of ISO 11922-1 .
n

applicable prior to storage.
d [3]
For a d of 12 to 1 000, the tolerance conforms to 0,5 grade M of ISO 11922-1 . The requirement for out-
n
of-roundness is only applicable prior to the pipe leaving the manufacturer's premises.

6.4 Wall thickness and their tolerances
The nominal wall thickness, e , is classified with the pipe series S. The nominal wall thickness corresponds to
n
the minimum allowable wall thickness.
The nominal wall thickness shall conform to Table 2, as appropriate to the pipe series.
The tolerance for wall thickness, e, shall conform to Table 3.
