As the automotive industry accelerates toward electrification, the need for clear, consistent language and safe practices for battery end-of-life management becomes critical. SAE J2974 (revised 2019) provides a common framework for understanding battery components, recycling technologies, and safety considerations. This…

Originally issued in 1965 and reaffirmed in February 2023, SAE J912 defines a standardized test method for determining block resistance and associated characteristics of automotive trim materials. This standard helps manufacturers assess the tendency of trim materials to stick together under…

SAE J3187-2023 provides recommended practices for applying System Theoretic Process Analysis (STPA) to evaluate safety-critical systems across any industry. This article highlights the key methodology steps, integration with existing safety processes, and lessons learned from the standard. Understanding the STPA…

Diesel fuel injection pumps feature several adjustable parameters that can affect exhaust emissions. Regulatory agencies such as the U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) require that these adjustments be protected from unauthorized tampering. SAE…

The Role of SAE J449 in Surface Texture Control Surface texture is a critical attribute in the design and manufacturing of surface vehicle components. It influences friction, wear, sealing, fatigue strength, and visual quality. SAE J449, first issued in 1953,…

⚠️ Important Note: SAE J2945/8-2024 is an Information Report intended solely for testing and evaluation purposes. The functional requirements described here must not be applied in production V2X deployments, as they are designed to support controlled experiments in mixed-equipage environments.…

The SAE J2056-2-2000 Information Report, formally titled Survey of Known Protocols, provides a structured summary comparison of protocols found in manufacturing, automotive, aviation, military, and computer applications. It is intended to serve as a reference for engineers evaluating Class C…

The SAE J2215 recommended practice describes a method for evaluating the conformance match between two mating surfaces, especially when using pressure sensitive adhesives (PSAs). By employing a Clear Coordinated Surface (CCS) tool, engineers can visualize and quantify the contact pattern,…

Mechanical prestressing is a proven approach for enhancing the fatigue life of metal components by introducing beneficial compressive residual stresses. The SAE J811 information report provides a comprehensive overview, covering techniques such as surface rolling, shot peening, coining, and explosive…

Engineers specifying surface discontinuity limits for threaded fasteners in fatigue applications have historically relied on SAE J123. However, this standard was cancelled in April 2012 after the SAE Fasteners Committee confirmed that ASTM F788/F788M (including Supplementary Requirement S1) provides equivalent…
