SAE International has updated what it calls a critical standard that helps engineers identify flaws in the design and assembly of ground vehicles. Understanding these flaws leads to their prevention, ensuring a better product for the consumer. The standard is J1739, Potential Failure Mode and Effects Analysis in Design (Design FMEA) and Potential Failure Mode and Effects Analysis in Manufacturing and Assembly Processes (Process FMEA).” It is a revision of the 2002 version. The standard includes updated charts for ranking failure modes and de-emphasizes the use of the Risk Priority Number as the primary factor in determining preventative or corrective actions. It also provides appropriate terms, worksheets, requirements, and recommendations to guide the user through the FMEA process. J1739 was revised by SAE International’s Automotive Quality and Process Improvement Committee, which represents thoughts and practices from a balanced selection of original equipment manufacturers and suppliers.
