EN ISO 23936-2:2011

Petroleum, petrochemical and natural gas industries - Non-metallic materials in contact with media related to oil and gas production - Part 2: Elastomers (ISO 23936-2:2011)

ISO 23936 describes general principles and gives requirements and recommendations for the selection and qualification of non-metallic materials for service in equipment used in oil and gas production environments, where the failure of such equipment could pose a risk to the health and safety of the public and personnel, or to the environment. It can be applied to help avoid failures of the equipment itself. It supplements, but does not replace, the material requirements given in the appropriate design codes, standards or regulations.
ISO 23936-2:2011 describes the requirements and procedures for qualification of elastomeric material used in equipment for oil and gas production.

Industries du pétrole, de la pétrochimie et du gaz naturel - Matériaux non métalliques en contact avec les fluides relatifs à la production de pétrole et de gaz - Partie 2: Élastomères (ISO 23936-2:2011)

L'ISO 23936 décrit des principes généraux et spécifie des exigences et des recommandations concernant la sélection et la qualification des matériaux non métalliques pour des équipements utilisés en production de pétrole et de gaz, lorsque la rupture d'un tel équipement pourrait présenter un risque pour la santé et la sécurité du public et du personnel ou pour l'environnement. Elle peut également contribuer à éviter des défaillances des équipements eux-mêmes. Elle complète, sans toutefois s'y substituer, les exigences concernant les matériaux dans les codes de conception, normes ou réglementations appropriés.
L'ISO 23936-2:2011 décrit les exigences et les modes opératoires de qualification des matériaux élastomères utilisés dans les équipements de production de pétrole et de gaz.

ISO 23936 opisuje splošna načela in podaja zahteve ter priporočila za izbor in razvrstitev nekovinskih materialov za servisiranje v opremi, ki se uporablja v okoljih za proizvodnjo nafte in plina, kjer lahko odpoved takšne opreme predstavlja tveganje za zdravje in varnost ljudi ter osebja ali tveganje za okolje. Uporablja se lahko za preprečevanje odpovedi opreme. Dopolnjuje, vendar ne nadomešča zahtev za material iz ustreznih standardov ali predpisov. Ta del standarda ISO 23936 opisuje zahteve in postopke za razvrstitev elastomernih materialov, ki se uporabljajo v opremi za proizvodnjo nafte in plina.

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 23936-2 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures
for petroleum, petrochemical and natural gas industries.

industries — Non-metallic materials in contact with media related to oil and gas production:
 Part 1: Thermoplastics
 Part 2: Elastomers
The following parts are planned:
 Part 3: Thermosets
 Part 4: Fibre-reinforced composite
 Part 5: Other non-metallic materials

ISO 23936-2:2011(E)
Introduction
ISO 23936 is intended to be of benefit to a broad industry group, ranging from operators and suppliers to
engineering companies and authorities. ISO 23936 covers relevant generic types of non-metallic material
(thermoplastics, elastomers, thermosetting plastics, fibre-reinforced plastics, etc.) and draws upon a wide
range of existing technical experience, which has never before been summarized in a technical standard.
ISO 23936 does not cover polymeric coatings such as thermal insulation and paint that are applied to the
outside of components but that are not in contact with oilfield fluids.
The evaluation and qualification process described in this part of ISO 23936 is intended to ensure that the
user of non-metallic materials has sufficient understanding and knowledge of the applicable materials to
obtain acceptable performance in the specified environment, and that the user can rely on stable quality to
meet given specifications. A quality system is useful to ensure compliance with the requirements of this part of
ISO 23936.
Successful qualification of a manufacturer and a specific material is intended to be valid for other projects and
different operators. The consideration of qualification of a ma
