1 Scope

This International Standard was formulated to provide the minimum acceptable requirements for subsurface safety valve (SSSV) equipment. It covers subsurface safety valves, safety valve locks, safety valve landing nipples and all components that establish tolerances and/or clearances which may affect performance or interchangeability of the SSSV equipment. Safety valve locks, safety valve landing nipples and SSSVs manufactured by different facilities or manufacturers may be supplied as separate items.

NOTE Limits: The subsurface safety valve is an emergency safety device, and is not intended or designed for operational activities, such as production/injection reduction, production stop, or as a backflow valve.
