Abstract
Overview - ISO/TS 5486:2025 (Metallographic determination of ferrite)
ISO/TS 5486:2025 is a Technical Specification from ISO that specifies a metallographic method to determine the maximum local ferrite content within an austenitic matrix of stainless steel. The document covers sampling, specimen preparation (grinding, polishing, etching), microscopic examination and three accepted evaluation methods (comparison chart, image analysis, and point counting). It is intended for laboratories, manufacturers and inspectors who need a repeatable, standards‑based procedure for ferrite determination in austenitic stainless steels.
