SAE J1739â„¢ MAY2026 describes Potential Failure Mode and Effects Analysis (FMEA) for design (DFMEA), supplemental FMEA for monitoring and system response (FMEA-MSR), and manufacturing and assembly processes (PFMEA). It provides terminology, requirements, recommendations, rating charts, risk prioritization methods, worksheet formats, and a structured six-step process for identifying, assessing, reducing, and communicating technical risk.
The standard supports cross-functional FMEA activities throughout product development, validation, production, and subsequent revisions. It includes guidance for system hierarchy, project planning, functional analysis, failure mode identification, effects and causes analysis, prevention and detection controls, severity, occurrence, detection, monitoring, action priority, special characteristics, recommended actions, effectiveness feedback, version control, and linkages among DFMEA, PFMEA, process flow diagrams, and process control plans.
This document was issued in July 1994, revised in January 2021, stabilized in May 2026, and supersedes SAE J1739 JAN2021. SAE has declared it stabilized and recommends that users verify the continued suitability of its requirements and references.
Application Scope: Automotive product design, mechatronic and software systems, manufacturing and assembly process development, quality engineering, reliability engineering, risk management, design verification and validation, production validation, and supplier or customer FMEA reviews.
