1.1This specification covers thermoplastic fluoropolymer-based materials, intended for use as an encapsulation material for downhole cables used during well completion by the petroleum and natural gas industries.
1.2The fluoropolymers covered by this specification include but are not limited to the following: ethylene tetrafluoroethylene (ETFE), polyethylene chlorotetrafluoroethylene (ECTFE), fluorinated ethylene propylene (FEP), polyvinylidene fluoride (PVDF), copolymers of PVDF, polychlorotrifluoroethylene (PCTFE), polytetrafluoroethylene (PTFE), and perfluoroalkoxy alkane (PFA).
1.3This specification establishes common temperature ratings for the encapsulation materials and also describes requirements for alternative temperature ratings.
1.4The applications for the encapsulation materials covered by this specification are all associated with downhole cables used during well completion. Such applications include, but are not limited to, the following: control lines (CL), tubing encased conductors (TEC), tubing encased fiber cables (TEF), and tubing encased power cables (TEPC). Other downhole cable products such as surface-controlled sub-surface safety valves (SCSSV or SSSV) and chemical injection lines/chemical injection tubes (CIL/CIT) are also covered by this specification.
1.5The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.
1.6This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.7This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
