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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

ISO 17484-1:2014(E)
Introduction
This part of ISO 17484 was developed in response to worldwide demand for minimum specification for
multi-layered pipes for indoor gas applications.
Multi-layered pipes are delivered generally as a complete system. Pipes, fittings, tools, etc., are not
compatible with components of another brand, generally. An advantage is that all components are
perfectly geared to one another, but for repair, the lack of compatibility might be problematic in the
future.
Safety of systems
Depending on the construction of the house, pipework layout and other local circumstances, it is possible
that additional safety devices are required to fulfil the demands of fire safety. Safety aspects of the
system are described in ISO 17484-2 and national regulations shall be taken into account.
Code of practice
The second part of ISO 17484 is the code of practice for installation.
Recommendations on design, construction and protection in case of fire of the gas indoor installation
are given in EN 1775.
References to ISO/TC 138/SC5 work
Test methods referred to in this part of ISO 17484 have been developed by SC 5 as far as possible.
However, not all test methods needed are in the working programme of SC 5. These test methods are
placed in Annexes B to K of this part of ISO 17484. It is planned that these tests will be developed as
International Standards in the future.
For multilayer pipe construction, consisting of a layer of a reference standard material, an adhesive and
a non-stress-designed layer, procedure I and the relevant product standards are followed for all aspects,
excluding the aspects of delamination and, if applicable, oxygen permeation.
For example, layers can have the following purposes:
— ability to withstand the pressure;
— ability to realize interlayer adhesion;
— ability to block or greatly diminish incoming UV and/or sunlight;
— ability to mechanically protect the outside layer;
— ability to control the longitudinal expansion;
— ability to give the multilayer pipe a colour (inside layer or outside layer).
Some characteristics can be combined in one layer.

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 17484-1 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the
transport of fluids, Subcommittee SC 4, Plastics pipes and fittings for the supply of gaseous fuels.
This second edition cancels and replaces the first edition (ISO 17484-1:2006) and ISO 17484-1:2006/Cor.1:2008,
of which have been technically revised.
ISO 17484 consists of the following parts, under the general title Plastics piping systems — Multilayer pipe
systems for indoor gas installations with a maximum operating pressure up to and including 5 bar (500 kPa):

ISO/DIS 17484-1
Introduction
This part of ISO 17484 was developed in response to worldwide demand for minimum specification for multi-
layered pipes for indoor gas applications.
Multi-layered pipes are delivered generally as a complete system. Pipes, fittings, tools, etc., are not
compatible with components of another brand, generally. An advantage is that all components are perfectly
geared to one another, but for repairing, the lack of compatibility might be problematic in the future.
Fire safety of systems
Depending on the construction of the house, pipework layout and other local circumstances, it is possible that
additional safety devices are required to fulfill the demands of fire safety. Safety aspects of the system will be
described in the planned Part 2.
Code of practice
The planned second part of ISO 17484 will be the code of practice for installation.
Recommendations on design, construction and protection in case of fire of the gas indoor installation are
given in EN 1775.
References to ISO/TC 138/SC5 work
Test methods referred to in this part of ISO 17484 have been developed by SC 5 as far as possible. However,
not all test methods needed are in the working programme of SC 5. These test methods are placed in
Annexes B to K of this part of ISO 17484. It is planned that these tests will be developed as International
Standards in the future.
For multilayer pipe construction, consisting of a layer of a reference standard material, an adhesive and a non-
stress-designed layer, procedure I and the relevant product standards are followed for all aspects, excluding
the aspects of delamination and, if applicable, oxygen permeation.
For example, layers can have the following purposes:
¾ ability to withstand the pressure;
¾ ability to realize interlayer adhesion;
¾ ability to block or greatly diminish incoming UV and/or sunlight;
¾ ability to mechanically protect the outside layer;
¾ ability to control the longitudinal expansion;
¾ ability to give the multilayer pipe a colour (inside layer or outside layer).
Some characteristics can be combined in one layer.

DRAFT INTERNATIONAL STANDARD ISO/DIS 17484-1
Plastics piping systems — Multilayer pipe systems for indoor
gas installations with a maximum operating pressure up to and
including 5 bar (500 kPa) —
Part 1:
Specifications for systems
1 Scope
This part of ISO 17484 specifies the general requirements and the performance requirements for multilayer
pipe systems based on pipes, fittings and their joints intended to be used for gas supply within buildings.
PE-X and PE * pipes composed of one stress-designed layer, adhesive and a barrier layer are also covered
by this part of ISO 17484.
This part of ISO 17484 gives guidance for the design of piping systems consisting of multilayer pipes based
on thermoplastics, for which at least 60 % of the wall thickness is polymeric material. Polymeric materials
intended for stress-designed layers and all inner layers are required to be polyethylene (PE) and/or
crosslinked polyethylene (PE-X) in accordance with Annex A of this part of ISO 17484. The outer layer of a
metal multilayer is required to be PE or PE-X. PE-RT is considered as PE but with specific properties
concerning hoop-stress performance (see 5.4.2.).
This part of ISO 17484 applies to systems that operate at temperatures of - 20 °C up to 60 °C.
For the purpose of this part of ISO 17484, crosslinked polyethylene (PE-X) and adhesive layers are
considered as thermoplastic materials.
For sizes greater than 63 mm the requirements of ISO 18225 have to be fulfilled in addition.
This part of ISO 17484 is applicable for piping systems used in buildings to supply gas with a maximum
1)
operating pressure up to and including 500 kPa (5 bar) .
This standard applies to the following fuels:
¾ Category D gaseous fuel: natural gas; see ISO 13623;
¾ Category E gaseous fuel: LPG vapour, and natural gas or LPG vapour; see ISO 13623.
* Note:The maximum operation pressure of PE 80 may be lower than 5 bar.
