This document specifies the characteristics and requirements for components such as pipes, fittings, and valves made from one of the following materials intended to be used for thermoplastics piping systems in the field of industrial applications above and below ground: — unplasticized polyamide (PA-U) NOTE 1 Requirements for industrial valves are given in this document and/or in other standards. This document is applicable to either PA-U pipes, fittings, valves, and their joints and to joints with components of other plastics and non-plastic materials, depending on their suitability, intended to be used for the conveyance of liquid and gaseous fluids as well as solid matter in fluids for industrial applications such as the following: — transport of oil, gaseous fuels and multiphase mixtures (exploration and production; general purpose hydrocarbon-based fluids); — transport of renewable gases (hydrogen, biomethane); — transport of contaminated sewer (e.g. contaminated with hydrocarbons); — transport of CO2 (carbon capture and utilisation or storage (CCUS)) NOTE 2 National regulations can apply. Other application areas are permitted if the requirements of this document and/or applicable national requirements are fulfilled. Characteristics and requirements which are applicable for PA-U are covered by the relevant clauses of this document. Those characteristics and requirements which are dependent on the material are given in the relevant normative annex A.

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.

components and system
1 Scope
This document specifies the characteristics and requirements for a piping system and its components such as
pipes, fittings, and valves, made from one of the following materialsunplasticized polyamide (PA-U) intended
to be used for thermoplastics piping systems in the field of industrial applications above and below ground:.
— — unplasticized polyamide (PA-U)
NOTE 1 Requirements forapplying to industrial valves are given in this document and/or in other standards.
This document is applicable to PA-U pipes, fittings, valves and their joints, and to joints with components of
other plastics and non-plastic materials, depending on their suitability, intended to be used for the conveyance
of liquid and gaseous fluids as well as solid matter in fluids for industrial applications such as the following:
— — transport of oil, gaseous fuels and multiphase mixtures (exploration and production; general purpose
hydrocarbon-based fluids);
— — transport of renewable gases (hydrogen, biomethane);
— — transport of contaminated sewer (e.g. contaminated with hydrocarbons);
— — transport of CO ([carbon capture and utilisation or storage (CCUS)))].
NOTE 2 National regulations can apply.
NOTE 3 Other application areas are permittedpossible if the requirements of this document and/or applicable
national requirements are fulfilled.
Characteristics and requirements which are applicable for PA-U are covered by the relevant clauses of this
document. Those characteristics and requirements which are dependent on the material are given in the
relevant normative Annex Aannex A.
