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 17467-2 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 first edition of ISO 17467-2 cancels and replaces the first edition of ISO 15439-2:2007, which has
been technically revised.
ISO 17467 consists of the following parts, under the general title Plastics piping systems for the supply of
gaseous fuels — Unplasticized polyamide (PA-U) piping systems jointed by solvent cement:
— Part 1: General
— Part 2: Pipes
— Part 3: Fittings

Introduction
Thin wall thickness unplasticized polyamide (PA-U) pipes and solvent cement joints are used typically
for low pressures, while thicker wall thickness pipes and butt fusion, electrofusion or mechanical joints
are typically used for high pressures.
For technical and safety reasons, it is not possible to mix the components of the two types of piping
system (thin wall thickness pipes cannot be jointed by butt fusion or mechanical joints and vice versa).
In particular, solvent cement joints must not be used for jointing for high pressure piping systems.
So for the time being, the standardisation programme dealing with unplasticized polyamide (PA-U)
piping systems for the supply of gaseous fuels is split into two series of International Standards, with
one series (ISO 17467) covering piping systems the components of which are connected by solvent
cement jointing and the other (ISO 16486) the components of which are connected by fusion jointing
and/or mechanical jointing. When more experience will be gained from the field, it might be reasonable
to merge ISO 17467 series and ISO 16486 series in one single series applicable to PA-U piping systems.
A similar series (ISO 17135) of International Standards for fusion and mechanically jointed plasticized
polyamide (PA-P) piping systems is in preparation.

Pipes
1 Scope
This part of ISO 17467 specifies the physical and mechanical properties of pipes made from unplasticized
polyamide (PA-U) in accordance with Part 1, intended to be buried and used for the supply of gaseous
fuels for maximum operating pressure up to and including 4 bar.
It also specifies the test parameters for the test methods to which it refers.
In addition, this part of ISO 17467 lays down dimensional characteristics and requirements for the
marking of pipes.
