适用范围：This International Standard provides the requirements for subsurface barrier valves and related equipment asthey are defined herein for use in the petroleum and natural gas industries. Included are the requirements fordesign, design validation, manufacturing, functional evaluation, repair, redress, handling and storage.Subsurface barrier valves provide a means of isolating the formation or creating a barrier in the tubular tofacilitate the performance of pre- and/or post-production/injection operational activities in the well.The subsurface barrier valve is not designed as an emergency or fail-safe flow controlling safety device.This International Standard does not cover installation and maintenance, control systems such as computersystems, and control conduits not integral to the barrier valve. Also not included are products covered underISO 17078, ISO 16070, ISO 14310, ISO 10432, ISO 10423 and the following products: downhole chokes,wellhead plugs, sliding sleeves, casing-mounted flow-control valves, injection valves, well-condition-activatedvalves or drill-stem test tools. This International Standard does not cover the connections to the well conduit.
