API Standard 6AV2 Second Edition PDF
This standard provides requirements for installing and maintaining safety valves. Included are requirements for receiving inspection, installation and maintenance, field and offsite repair, testing procedures with acceptance criteria, failure reporting, and documentation.
“Safety valve” as used in this standard denotes a surface safety valve (SSV), an underwater safety valve (USV), or a boarding shutdown valve (BSDV). Power and control systems for safety valves are not included.

— The requirements for off-site repair of safety valves now refer to API 6AR.
