is an international standard titled "Petroleum, petrochemical and natural gas industries — Pressure-relieving and depressuring systems." It is technically identical to API Standard 521
ISO 23251 is an international standard that provides detailed guidance on the design, sizing, and selection of pressure-relieving and depressuring systems for petroleum, petrochemical, and natural gas industries. It is technically identical to the widely used API Standard 521 .
: The standard covers the determination of relieving rates, causes of overpressure (such as fire, power failure, or chemical reactions), and the design of disposal systems like flare headers and vents. iTeh Standards Relationship with API Standard 521 ISO 23251 is technically aligned with API Standard 521 iTeh Standards Harmonisation iso 23251 pdf
Q: What is the purpose of ISO 23251? A: The purpose of ISO 23251 is to provide a framework for assessing the functional ability and performance of older adults, with a focus on their health and wellness.

ISO 23251 is an international standard for "Petroleum, petrochemical and natural gas industries - Drilling and production equipment - Electric subsea actuated intervention valves and valve systems for control of wellhead and Christmas tree equipment".
"Initiate emergency depressuring!" Elias shouted. "Follow the ISO 23251 guidelines for blowdown. We need to drop that vessel pressure to 50% of the design pressure within fifteen minutes."
This means ISO 23251 does not stand alone. To have a complete and up-to-date design basis, you must reference both documents. ISO 23251 acts as an amendment, providing specific exceptions and additions to the 6th edition of API 521.
