The following table summarizes the evolution from the 11th through the anticipated 13th Edition:
The API 610 13th Edition specifies requirements for three primary pump classifications:
| Category | 12th Edition (2021) | 13th Edition (Draft) | | :--- | :--- | :--- | | | Standard Baseplates (Normative) | Removed | | Appendix O (repositioned) | N/A | Special-purpose Centrifugal Pumps (Informative) | | Appendix J | Determination of Residual Unbalance | Procedure for the Verification of Residual Unbalance | | Appendix H | Pump Parts Materials | Pump Parts Materials (Added new Table H.5) | Api 610 13th Edition
For reliability engineers, understanding the nuance is key. Let’s review the most frequently referenced sections in the .
Modified minimum curve rise guidelines for pumps running in parallel to mitigate system hunting. 3. Strict Emission Containment & Seal Chamber Integration The following table summarizes the evolution from the

Evolution of a Standard: What’s on the Horizon for API 610 13th Edition? American Petroleum Institute (API)
The release of the marks a significant evolution in pump design, safety protocols, and operational longevity. While the previous 12th Edition (ISO 13709) set a high bar, the 13th edition introduces critical updates aimed at reducing lifecycle costs, improving mechanical seal integrity, and addressing carbon emission mandates.
D --> D1[VS1, VS2, VS3] D --> D2[VS4, VS5, VS6, VS7]
API 610 has stood for decades as the most trusted standard for heavy‑duty centrifugal pumps in the hydrocarbon processing industry. The forthcoming 13th Edition continues this tradition—not by reinventing the wheel, but by carefully refining the details. The removal of the baseplate appendix, the renaming of the unbalance verification appendix, and the addition of new material tables all point toward a standard that values clarity, practicality, and alignment with current industrial practice.
