It allows facilities to use standard material safety valves rather than upgrading the entire valve body to expensive specialized alloys.

. This part of the ISO 4126 series is indispensable for ensuring that safety systems—not just the individual valves—function correctly as a final line of defense. ISO - International Organization for Standardization Scope and Application

High-pressure steam lines, process gases, and air systems.

Covers the arrangement of multiple safety devices in series or parallel and includes rules for isolating valves (which must not be able to inadvertently isolate the safety system).

The standard operates under several specific assumptions that users must understand:

— Lists other standards referenced throughout the document.

The standard differentiates between:

When purchasing the official ISO 4126-9 PDF, users should be aware of certain technical restrictions that come with the copyright-protected document:

Each scenario demands a different sizing equation.

Pressure vessels and piping systems are ubiquitous in modern industrial processing. To prevent catastrophic failure due to excessive pressure, safety devices—primarily safety valves and bursting discs—are installed. However, the presence of a safety device does not guarantee safety if the device is improperly installed or applied.
