ISO 23936-2-2011 pdf download.Petroleum, petrochemical and natural gas industries – Non-metallic materials in contact with media related to oil and gas production – Part 2: Elastomers.
ISO 23936 describes general pnnciples 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.
This part of ISO 23936 describes the requirements and procedures for qualification of elastomenc material used in equipment for oil and gas production.

3 Terms, definitions and abbreviated terms
For the purposes of this document, the following terms, definitions and abbreviated terms apply.
3.1 Terms and definitions
3.1.1 accelerated test
test undertaken under conditions designed to speed material deterioration
NOTE This is usually accomplished by increasing temperature, in order to raise chemical reaction rates, but fluid concentration and stress are vanables which can also be manipulated.
3.1.2 asset operator
person who operates an asset, who has knowledge of well parameters and wt’io transmits this information to the user (3.1.15)
NOTE I An asset can be a well, a production train, a plant, etc.
NOTE 2 Well parameters can be fluid exposure, temperatures, pressures, duration, etc.
3.1.3 compression set
difference between the original sample height and the post-test height. divided by the interference, expressed as a percentage.ISO 23936-2 pdf download.
