ISO 17078-2:2007提供了在全球石油和天然气工业中使用的侧袋式心轴（以下简称流量控制装置）中使用的地下流量控制装置的要求。这包括指定，选择，设计，制造，质量控制，测试和流量控制装置运输准备的要求。此外，它还包括有关性能测试和校准程序的信息。 流量控制装置的安装和检修超出了ISO 17078-2:2007的范围。此外，ISO 17078-2:2007不适用于中心心轴或可回收油管应用中的流量控制装置。 ISO 17078-2:2007不包括侧袋心轴，运行，拉动和翻转工具以及其他ISO规范中可能涵盖或可能不涵盖的闩锁的要求。二手流量控制装置的修复不在ISO 17078-2:2007的范围之内

ISO 17078-2:2007 provides requirements for subsurface flow-control devices used in side-pocket mandrels (hereafter called flow-control devices) intended for use in the worldwide petroleum and natural gas industry. This includes requirements for specifying, selecting, designing, manufacturing, quality-control, testing and preparation for shipping of flow-control devices. Additionally, it includes information regarding performance testing and calibration procedures. The installation and retrieval of flow-control devices is outside the scope of ISO 17078-2:2007. Additionally, ISO 17078-2:2007 is not applicable to flow-control devices used in centre-set mandrels or with tubing-retrievable applications. ISO 17078-2:2007 does not include requirements for side-pocket mandrels, running, pulling, and kick-over tools, and latches that might or might not be covered in other ISO specifications. Reconditioning of used flow-control devices is outside of the scope of ISO 17078-2:2007.
