This recommended practice from SAE J421-2018 provides a structured approach for rating steel cleanliness using magnetic particle inspection. It outlines procedures for sampling, specimen preparation, magnetization, and indication counting to assess non-metallic inclusions. Sample Selection and Specimen Preparation Sampling should…

Note: SAE J2057‑2 (202212) is an information report, not a recommended practice. It is intended to help system engineers understand and address issues specific to Class A multiplexed actuators. Class A Multiplexing Actuators: Overview and Actuator Types Class A multiplexing…

This article explores the two prevalent multiplex architecture strategies for vehicle networks as described in SAE J2057-4: Single Network Architecture and Multiple Network Architecture. We examine the three classes of multiplex networks, the trade-offs between architectures, and key design considerations…

Ensuring that wheel finishes withstand the chemical environment they encounter is critical for both appearance and durability. SAE J2792 (SEP2015) provides a standardized methodology for testing the chemical compatibility of aluminum wheel and trim surface finishes with tire cleaners, wheel…

🔍 Accurate measurement of diesel exhaust emissions is critical for environmental monitoring and engine development. While regulated emissions have well-defined protocols, nonregulated species such as aldehydes, carbonyl compounds, sulfates, and polycyclic aromatic hydrocarbons (PAH) require specialized chemical methods. SAE J1936,…

Fasteners are critical components in ship systems and equipment, where failure can lead to costly repairs and safety hazards. The recently updated SAE J2280-2021 standard provides comprehensive guidance on fastener selection and identification, aligning with Navy and industry standards. Whether…

SAE J2907 provides a standardized test procedure for electric traction drive motors, including their mating power converters and controllers. This recommended practice, stabilized in 2023, ensures repeatable measurements for torque, power, and endurance. It is essential for engineers developing electrified…

Understanding how to properly test and evaluate leakage in air-to-air charge air coolers (CACs) is critical for engine performance and reliability. SAE J2679 (cancelled in 2010 and superseded by SAE J1726) provides a clear framework for acceptable leakage rates, standardized…

The SAE J2177 standard provides a comprehensive, industry-recognized procedure for measuring power delivered through the drive tires of heavy-duty road vehicles. Designed for DOT Class 6, 7, and 8 vehicles with compression ignition engines, this recommended practice ensures consistency, repeatability,…

SAE J2392 has been reaffirmed in 2024 to define tolerances and attributes of cold rolled strip steels. This recommended practice helps engineers understand the nuances between cold rolled strip and sheet, enabling precise material selection for automotive and other applications.…
