Petroleum and natural gas industries. Downhole equipment. Subsurface safety valve equipment1 Scope This International Standard provides the minimum acceptable requirements for subsurface safety valves (SSSVs). It covers subsurface safety valves including all components that establish tolerances and or clearances which may affect performance or interchangeability of the SSSVs. It includes repair operations and the interface connections to the flow control or other equipment, but does not cover the connections to the well conduit. NOTE

Why should you use BS EN 15132 - Requirements for mobile waste container shells

The number of parameters for the procedure involved in the electrothermal atomization is far larger than in flame atomization

This improves the reliability of destructive tests on welds in metallic materials

PD CLC/TS 50586 gives an essential feature of the protocol

In the case of power operated valves

The establishment and implementation of an organization’s information security management system are influenced by the organization’s needs and objectives

and enhancing the organization's ability to improve its products and services

While this standard is intended for use by bodies concerned with recognizing the competence of certification/registration bodies many of its provisions may be useful in second-party assessment procedures
