SAE Standards Interpretation
The SAE J2754-2019 standard provides a consistent, industry-recognized method for approximating the volume of material that can be contained in a grapple mounted to an excavator and operated through its bucket linkage. This rating is based on a geometric decomposition…
The SAE J2763-2015 standard provides a reproducible method for measuring refrigerant loss from mobile air conditioning (MAC) systems using a controlled Mini-Shed chamber. By simulating real-world temperature profiles and including system seasoning, this procedure enables engineers to estimate annual emissions…
SAE J2747-2019 establishes a standardized bench test method for measuring airborne noise from positive displacement hydraulic pumps used in ground vehicle power steering systems. This recommended practice ensures consistent, repeatable sound power measurements across different test labs by specifying pump…
SAE J2748 (2006) defines a standardized set of VHDL-AMS packages for modeling statistical variations in design parameters. Designed primarily for automotive electrical, electronic, and mechatronic systems, the standard enables engineers to perform Monte Carlo simulations and extreme value analyses by…
The SAE J2750 standard, revised in February 2025, provides a uniform system for states and provinces to assign identification numbers to vehicles and watercraft that lack federally certified Vehicle Identification Numbers (VINs). By following this recommended practice, agencies can ensure…
Overview of SAE J2743_202312 SAE J2743_202312 defines a standardized methodology for rating the size of air compressors used in truck and bus brake systems. Reaffirmed in December 2023 to comply with SAE’s five-year review cycle, this recommended practice establishes a…
The SAE J2744 standard, stabilized in March 2020, specifies requirements for a built-in service port (valve assembly) used in vehicles with Enhanced Evaporative Emissions requirements and OBD II systems. The service port provides non-destructive access for testing system integrity by…
Understanding the Software Assessment Repository (SAR) The rapid growth of feature content in automotive electronics has introduced new suppliers whose software development qualifications are often unclear. To address this, SAE J2746 establishes a web-based Software Assessment Repository (SAR) where organizations…
SAE J273, published by SAE International and cancelled in 2006, established a standardized approach for creating Vehicle Identification Numbers (VINs) for passenger cars. It supplemented SAE J272c and was later superseded by updates to SAE J272. This article explores the…
SAE J2742 standard establishes minimum construction and performance requirements for a combination cable consisting of 11 conductors and two twisted pairs for truck, trailer, and dolly applications in 12 VDC nominal systems using SAE J2691 connectors. The cable integrates power…
