3? Terms? and? Defnitions For the purposes of this document, the terms and defnitions given in ISO 9000 and the following apply. 3.1 assembly (noun) Product comprised of more than one component. 3.2 ambient temperature Prevailing temperature at test site. 3.3 base design Design of a specifed size, type, and model of SCIV that has passed the requirements of Annex B and meets the requirements of this specifcation. 3.4 blockage barrier Obstacle or impediment to fow and/or pressure. 3.5 casing Pipe extending from the surface and intended to line the walls of a drilled well. 3.6 casing-mounted? fow-control? valves Downhole valves permanently installed as a component of the casing or liner (pipe not extending from the sur- face and intended to line the walls of a drilled well). 3.7 city water Water that is provided by the local water utility system, which may include inhibitors.
3.8 closing mechanism Device designed to block or impede fow at a designated point when closed. 3.9 common hardware Non-traceable nuts, bolts, washers, screws, and spacers. 3.10 design margin Ratio of the material minimum yield stress divided by the actual design stress in a component at the rated con- ditions. 3.11 design validation Process of proving a design by testing to demonstrate conformity of the product to design requirements. 3.12 design? verifcation Process of examining the result of a given design or development activity to determine conformity with specifed requirements. 3.13 downhole choke Downhole device used to restrict fow rates through its ID and not intended to seal as a barrier. 3.14 drift diameter Minimum ID of a SCIV, expressed as the OD of the drift bar used during assembly verifcation. 3.15 drill-stem test tools Downhole tools temporarily set in place for the purpose of evaluating the production potential of the chosen formation. 3.16 end connection SCIV equipment/tubular connecting interface. 3.17 environment Set of conditions to which a product is exposed. 3.18 external means Signal or method used to actuate a subsurface completion isolation (barrier) valve that is instigated by human intention. 3.19 ft Geometric relationship between parts. NOTE This includes the tolerance criteria used during the design of a part and its mating parts, including seals adjusted to or shaped for their purpose.
3.21 functional? specifcation Features, characteristics, process conditions, boundaries, and exclusions defning the performance and use requirements of the products. 3.22 functional test Test processes performed to confrm proper operation of SCIV products. 3.23 heat Material originating from a fnal melt, or for re-melt alloys, the raw material originating from a single re-melt ingot. 3.24 heat-lot Material or components having undergone the same process or series of processes and being traceable to one heat of material. 3.25 heat treat lot A group (lot) of components of material that have undergone the same process or series of processes in a single heat treatment furnace load or continuous furnace run and are uniquely identifed. 3.26 heat treatment Alternate steps of controlled heating and cooling of materials for the purpose of changing mechanical properties. 3.27 informative Information intended to enlighten the user/purchaser or supplier/manufacturer, without containing requirements. 3.28 injection valve Downhole valve that is normally closed and opened by injected fow within the primary conduit and used for long- term well injection to prevent backfow. 3.29 interchangeability State of conforming within specifed tolerances, to both ft and function of a safe design but not necessarily to the form. 3.30 job-lot Batch of material or components that have undergone the same process or series of processes. NOTE This may include more than one heat. 3.31 life cycle Expected period of time or specifed number of actuations that the product shall function according to the sup- plier/manufacturer’s specifcations.
