22、d 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 technica
23、l 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 ele
24、ctrotechnical 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 th
25、e 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 ide
26、ntifying 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. ISO 23936 consists of the following parts, under the general title Petroleum, petrochemical and nat
27、ural gas 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 BS EN ISO 23936-2:2011ISO 23936-2:
28、2011(E) ISO 2011 All rights reserved vIntroduction 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, thermosett
29、ing 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
30、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
31、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 proj
32、ects and different operators. The consideration of qualification of a manufacturer is at the discretion and determination of the purchaser, normally on the basis of documentation provided by the manufacturer, as required in this part of ISO 23936 or any specific additional documentation. The purchas
33、er is responsible for ensuring (if necessary, with external competence) that the manufacturers selected are qualified. This part of ISO 23936 is based on NORSOK standard M-710.

34、eum, petrochemical and natural gas industries Non-metallic materials in contact with media related to oil and gas production Part 2: Elastomers 1 Scope ISO 23936 describes general principles and gives requirements and recommendations for the selection and qualification of non-metallic materials for
35、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,
36、 the material requirements given in the appropriate design codes, standards or regulations. This part of ISO 23936 describes the requirements and procedures for qualification of elastomeric material used in equipment for oil and gas production. 2 Normative references The following referenced documen
