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
ISO 17484-1:2014 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 ISO 17484-1:2014. ISO 17484-1:2014 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 ISO 17484-1:2014. ISO 17484-1:2014 applies to systems that operate at temperatures of −20 °C up to +60 °C. For the purpose of ISO 17484-1:2014, 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. ISO 17484-1:2014 is applicable for piping systems used in buildings to supply gas with a maximum operating pressure up to and including 500 kPa (5 bar). ISO 17484-1:2014 applies to the following fuels: Category D gaseous fuel: natural gas; Category E gaseous fuel: LPG vapour, and natural gas or LPG vapour.

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.
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
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives
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. Details of any
patent rights identified during the development of the document will be in the Introduction and/or on
the ISO list of patent declarations received. www.iso.org/patents

The committee responsible for this document is 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), which has been technically
revised. It also incorporates ISO 17484-1:2006/Cor.1:2008.
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):
— Part 1: Specifications for systems
— Part 2: Code of practice
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 an
