ISO 23251 is the primary international standard for the design, selection, and application of in the hydrocarbon industry. While it is developed by the International Organization for Standardization (ISO), it is often considered the global counterpart to the API Standard 521 . Overview of ISO 23251

The standard outlines the methods for designing systems that rapidly reduce the pressure in equipment, which is vital for preventing catastrophic failures during a fire. ISO 23251 vs. API 521 Officially titled Petroleum

Moving away from solely relying on older, empirical pool fire tests.

Calculating radiation levels, noise levels, and atmospheric dispersion to ensure safety at grade level. ISO 23251 vs. API RP 521: What is the Difference?
