The standard applies to several types of small-bore valves used in instrumentation networks, including:

Covers ratings up to 15,000 psi (103.4 MPa) at a reference temperature of 100°F (38°C). mss sp99 pdf

These are non-destructive tests that must be performed on every production valve before shipment, ensuring manufacturing quality is consistent with the qualified design.

MSS SP-99 applies to a broad category of small-bore valves—typically —manufactured from steel or other alloys. These valves are engineered to withstand extreme conditions, with pressure ratings as high as 15,000 psi at ambient temperatures (100 °F). The standard is design-neutral, meaning it does not limit manufacturer innovation; instead, it provides a framework that can be applied to various valve types, including: Needle Valves : For precise flow regulation. Ball and Plug Valves : For rapid isolation.

The standard ensures reliability in high-pressure measurement and control applications by detailing specific requirements:
