As of April 2026, API 610 12th Edition (released January 2021) remains the current active standard for centrifugal pumps in the petroleum, petrochemical, and natural gas industries. While the industry often anticipates a "13th Edition" based on the American Petroleum Institute's typical 5-year review cycle, it has not yet been officially published.

: Updated criteria for bearing selection now include specific energy density considerations, particularly for large pipeline pumps. Hydrocarbon Processing Core Classifications in API 610 Api 610 13th Edition
One of the most significant structural changes in this edition is the adoption of . Previously, API 610 was adopted as ISO 13709. In the 13th Edition, API has adopted the ISO standard back as an API document, creating a unified global standard. As of April 2026, API 610 12th Edition
The American Petroleum Institute (API) standard 610 is the global benchmark for centrifugal pumps used in the petroleum, petrochemical, and natural gas industries. As processing plants evolve toward higher pressures, extreme temperatures, and more aggressive fluids, the standard must adapt. Hydrocarbon Processing Core Classifications in API 610 ISO
