Loss of cooling water or electrical power, causing sudden thermal expansion or loss of condensation capabilities.
ISO 23251 is an indispensable tool for any engineer or safety professional involved in the oil, gas, and petrochemical industries. It provides the authoritative framework for designing systems that protect against overpressure events.
I’m unable to provide a direct PDF file or a link to download due to copyright restrictions. However, I can give you a detailed write‑up about the standard, its scope, and how you can legally obtain it.
However, this direct equivalence has changed. The . This means the two documents are no longer identical. ISO 23251 now serves as an addendum, providing international perspectives and updates that apply on top of the API 521 framework.

Inadvertent valve closures or thermal expansion of blocked-in liquids.
Loss of cooling water, electrical power, or instrument air.

In a fire, metal loses its strength quickly under high pressure. ISO 23251 outlines the criteria for emergency depressurizing systems. It states how fast a system must drop its pressure (typically reducing equipment pressure to 100 psig or 50% of the design pressure within 15 minutes) to prevent a structural breach. Pillar 4: Environmental and Acoustic Considerations
Safe dispersion of non-hazardous or low-risk vapors.
