SAE Standards Interpretation
SAE J235 is a recommended practice that establishes test methods for electric blower motor switches used in vehicle blower systems. The standard ensures that switches can withstand extreme temperatures, prolonged cycling, and maintain low electrical resistance over time. Below we…
SAE J2360-2022 defines the physical, chemical, and performance requirements for automotive gear lubricants that surpass API GL-5 classifications. These lubricants are formulated for hypoid gear units operating under severe conditions such as high-speed/shock load and low-speed/high-torque, requiring robust extreme pressure…
Overview of SAE J2354-2019 SAE J2354-2019 defines message sets and data frames for Advanced Traveler Information Systems (ATIS) used in surface vehicle communications. Originating from the U.S. National ITS Architecture, this standard covers a wide range of traveler information services…
The SAE J2357-2012 standard provides comprehensive recommendations for the design, performance, and testing of electronically driven and controlled exterior lighting systems in automotive applications. It serves as a critical reference for engineers developing electronic modules for headlamps, signal lamps, and…
The SAE J2358 standard is the definitive guide for designing, manufacturing, and operating low-speed vehicles (LSVs) intended for public road use. The 2022 revision brings important updates that reflect technological advances, new safety data, and changing mobility needs. This article…
In 1997, the SAE In-Vehicle Systems Interface Committee conducted a survey of Mayday system manufacturers to determine whether the emerging SAE J2313 message set architecture aligned with commercial designs. The results, published as SAE J2352-1998, provided critical insights into the…
The SAE J2353-2019 standard provides a comprehensive data dictionary for Advanced Traveler Information Systems (ATIS). By defining a consistent set of data element names, definitions, and types, it enables different ATIS implementations to share information seamlessly. This standard covers directory…
SAE J2348-2024 establishes minimum performance requirements and uniform test procedures for switches that activate electric or electro-pneumatic windshield washer systems in trucks, buses, and multipurpose passenger vehicles with a gross vehicle weight (GVW) of 4500 kg (10,000 lb) or greater.…
The SAE J2349-2024 recommended practice sets forth minimum performance requirements and uniform test procedures for electric or electro-pneumatic windshield wiper switches used in trucks, buses, and multipurpose vehicles with a gross vehicle weight (GVW) of 4500 kg (10,000 lb) or…
SAE J234 is a recommended practice that defines the testing and performance requirements for electric windshield washer switches used in automotive applications. This standard ensures that switches can withstand extreme temperatures, endure repeated cycling, and maintain low contact resistance over…
The SAE J2342 standard provides a systematic method for identifying end mills using a 21‑ or 37‑position numbering system. Designed for cataloging and supplying these tools, it reduces ordering ambiguity by fully describing dimensions, types, materials, and special features. The…
SAE J2343-2018 is a stabilized recommended practice that provides guidelines for the construction, operation, and maintenance of LNG‑fueled medium and heavy‑duty vehicles. Developed with a Failure Modes and Effects Analysis (FMEA) and a thorough review of existing codes, it aims…
