for quality assurance. It supplements but does not replace, the material requirements given in the
appropriate design codes, standards or regulations.
This document addresses the resistance of thermoplastics to the deterioration in properties that can
be caused by physical or chemical interaction with produced and injected oil and gas-field media, and
with chemical treatment. Interaction with sunlight and ionizing radiation are excluded from the scope
of this document.
This document is not necessarily suitable for application to equipment used in refining or downstream
processes and equipment.
The equipment considered includes, but is not limited to, non-metallic pipelines, piping, liners, seals,
gaskets and washers.
Blistering by rapid gas decompression is not included in the scope of this document.
This document applies to the assessment of the stability of non-metallic materials in simulated
hydrocarbon production conditions to aid the selection of materials for equipment designed and
constructed using conventional design criteria. Designs utilizing other criteria are excluded from its

Le présent document donne les principes généraux et spécifie les exigences et recommandations pour l'évaluation de la stabilité des matériaux non métalliques destinés aux équipements utilisés dans des environnements d'exploration et de production de l'industrie pétrolière et gazière. Ces informations viennent en complément à la sélection des matériaux. Elles peuvent être appliquées pour aider à prévenir les défaillances coûteuses résultant de la dégradation de l'équipement lui-même, ce qui pourrait présenter un risque pour la santé et la sécurité du public et du personnel ou pour l'environnement. Le présent document fournit en outre des recommandations concernant l'assurance qualité. Il complète, sans toutefois s'y substituer, les exigences concernant les matériaux dans les codes, normes ou autres réglementations appropriés de construction.
Le présent document traite de la résistance des thermoplastiques à la détérioration des propriétés qui peut être provoquée par une interaction physique ou chimique avec les fluides produits et injectés dans les gisements pétroliers et gaziers, ainsi qu'avec les produits de traitements chimiques. Les interactions avec la lumière du soleil et les rayonnements ionisants sont exclues du domaine d'application du présent document.
Le présent document ne convient pas nécessairement à des équipements utilisés dans des processus et des équipements de raffinage ou en aval.
Les équipements considérés incluent, mais sans s'y limiter, les pipelines, les conduites, les chemisages, les joints et les joints d'étanchéité ainsi que les rondelles non métalliques.
Le cloquage résultant de la décompression rapide du gaz est exclu du domaine d'application du présent document.

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 (see 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 (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see
www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 67, Oil and gas industries including lower
carbon energy, in collaboration with the European Committee for Standardization (CEN) Technical
Committee CEN/TC 12, Materials, equipment and offshore structures for petroleum, petrochemical and
natural gas industries, in accordance with the Agreement on technical cooperation between ISO and
CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 23936-1:2009), which has been
technically revised.
The main changes are as follows:
— added a short-term, single temperature 28-day non-H S material stability evaluation as Level 2;
2
— added a 56-day total duration target for the traditional three temperature Arrhenius material
degradation evaluation as Level 3 and this is very similar to the previous edition;
— moved the life estimation analysis requirement to Level 4 and this new section has a 180-day total
duration target for the Arrhenius material degradation evaluation;
— added life estimation analysis examples for plastics.
A list of all parts in the ISO 23936 series can be found on the ISO website.

Introduction
Non-metallic materials are used in the petroleum, petrochemical and natural gas industries for a wide
range of components. The purpose of this document is to establish requirements and guidelines for
systematic and effective planning, for non-metallic material selection to achieve cost effective technical
solutions, taking into account possible constraints due to safety and/or environmental issues.
This document will be of benefit to a broad industry group ranging from operators and suppliers to
engineers and authorities. It covers relevant generic types of non-metallic material (e.g. thermoplastics,
elastomers, thermosetting plastics) and includes the widest range of existing technical experience.
Coatings are excluded from the scope of this document.
This document complements the ISO 15156 series on metallic materials in sour service. It differs in the
form of guidance provided to the user related to the potential degradation of desired properties when
used in equipment for oil and gas production environments. The ISO 15156 series provides application
limits and qualification requirements for metallic materials in H S-containing environments, which are
2
related solely to relevant environmentally assisted cracking mechanisms.
This document recognizes that a wider range of compounds and parameters influence the degradation
of non-metallic materials and thus provides guidance to permit selection of materials for hydrocarbon
exploration and production applications based upon stability in appropriate test conditions.

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 (see 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 (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/
iso/ foreword .html.
This document was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore
structures for petroleum, petrochemical and natural gas industries.
This second edition cancels and replaces the first edition (ISO 23936-1:2009), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— adds a short term, single temperature 28 day non-H S material stability evaluation as Level 2;
2
— adds a 56 day total duration target for the traditional three temperature Arrhenius material
degradation evaluation as Level 3 and this is very similar to the previous edition;
— moves the life estimation analysis requirement to Level 4 and this new section has a 180 day total
duration target for the Arrhenius material degradation evaluation;
— adds life estimation analysis examples for plastics.
A list of all parts in the ISO 23936 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
Non-metallic materials are used in the petroleum, petrochemical and natural gas industries for a wide
range of components. The purpose of this document is to establish requirements and guidelines for
systematic and effective planning, for non-metallic material selection to achieve cost effective technical
solutions, taking into account possible constraints due to safety and/or environmental issues.
This document will be of benefit to a broad industry group ranging from operators and suppliers to
engineers and authorities. It covers relevant generic types of non-metallic material (e.g. thermoplastics,
elastomers, thermosetting plastics) and includes the widest range of existing technical experience.
Coatings are excluded from the scope of this document.
This document complements the document for metallic materials in sour service (ISO 15156 series).
It differs in the form of guidance provided to the user related to the potential degradation of desired
properties when used in equipment for oil and gas production environments. The ISO 15156 series
provides application limits and qualification requirements for metallic materials in H S-containing
2
environments, which are related solely to relevant environmentally assisted cracking mechanisms.
This document provides general principles, requirements and recommendations for the assessment
of non-metallic materials’ comparative stability to aid selection and quality assurance. The document
recognizes that a wider range of compounds and parameters influence the degradation of non-metallic
materials and thus provides guidance to permit selection of materials for hydrocarbon exploration and
production applications based upon stability in appropriate test conditions.
This document applies to the assessment of the stability of non-metallic materials in simulated
hydrocarbon production conditions to aid the selection of materials for equipment designed and
constructed using conventional design criteria. Designs utilizing other criteria are excluded from its
scope.

DRAFT INTERNATIONAL STANDARD ISO/DIS 23936-1:2021(E)
Petroleum, petrochemical and natural gas industries —
Non-metallic materials in contact with media related to oil
and gas production —
Part 1:
Thermoplastics
CAUTION — Non-metallic materials selected using the parts of ISO 23936 are resistant to the
given environments in the petroleum and natural gas industries, but not necessarily immune
under all service conditions. This document allocates responsibility for suitability for the
intended service in all cases to the equipment user.
1 Scope
This document presents general principles and gives requirements and recommendations for the
assessment of the stability of non-metallic materials for service in equipment used in oil and gas
exploration and production environments. This information aids in material selection. It can be applied
to help avoid costly degradation failures of the equipment itself, which could pose a risk to the health
and safety of the public and personnel or the environment. This document also provides guidance
for quality assurance. It supplements but does not replace, the material requirements given in the
appropriate design codes, standards or regulations.
This document addresses the resistance of thermoplastics to the deterioration in properties that can
be caused by physical or chemical interaction with produced and injected oil and gas-field media, and
with chemical treatment. Interaction with sunlight and ionizing radiation are excluded from the scope
of this document.
This document is not necessarily suitable for application to equipment used in refining or downstream
processes and equipment.
The equipment considered includes, but is not limited to, non-metallic pipelines, piping, liners, seals,
gaskets and washers.
Blistering by rapid gas decompression is not included in the scope of this document.
