The SAE J3105/3 recommended practice defines an enclosed pin and socket connection interface for conductive automated charging devices (ACD) in electric vehicles. Designed for power transfer from 32 kW up to 1+ MW, this standard prioritizes safety, interoperability, and reliability…
In the rapidly evolving fields of vacuum excavation and sewer cleaning, clear and consistent terminology is essential for safety, maintenance, and communication across teams and manufacturers. SAE J3106-2019 addresses this need by providing a comprehensive standard that defines common terms,…
The SAE J3107:2021 standard establishes comprehensive safety requirements for the design, construction, operation, and maintenance of vacuum excavation and sewer cleaning equipment. This article highlights the most significant updates and critical safety measures that engineers and operators must understand. 🛠️…
The SAE J3105 standard has been revised to address the evolving needs of heavy-duty electric vehicle (EV) charging infrastructure. This update introduces critical features for automated connection devices (ACDs), enabling safe and efficient high-power charging across on-route and depot environments.…
SAE J3105/2 is a recommended practice that defines the conductive automated connection device (ACD) interface for heavy-duty on-road vehicles, specifically using a vehicle-mounted pantograph configuration, also known as “bus-up.” This standard enables hands-free, vertical engagement of the power transfer system,…
This SAE Recommended Practice establishes requirements for non-metallic (plastic) threaded caps used in engine cooling systems, including radiators and surge tanks. It defines compatible geometries for both plastic and metallic filler necks, focusing on sealing, thread compatibility, and safety through…
The SAE J3098-2017 standard provides a comprehensive framework for front decorative lamps—also known as signature or accent lamps. These lighting devices are intended solely for aesthetic enhancement and must not compromise the function of regulated lighting. This article covers the…
The SAE J3099-2024 Recommended Practice provides updated methods for establishing the driver workspace, including critical reference points for seating and steering wheel positioning. This standard supersedes earlier practices SAE J4002, J4003, J4004, and updates the accommodation models from SAE J1516…
The U.S. vehicle fleet is older than ever, with a median age exceeding 12 years. Yet the standard for headlamp lens durability—SAE J576—has remained anchored to a three-year outdoor weathering test on coated plaques. This mismatch has led to widespread…
The SAE J3094 standard, revised in February 2023, defines a common set of thermodynamic test conditions for evaluating internal heat exchangers (IHX) used in mobile air-conditioning systems with R-134a or R-1234yf refrigerants. This revision updates scaling limits based on bench…
