Rainflow cycle counting is the most widely accepted method for extracting fatigue-relevant cycles from variable amplitude load histories. However, the usefulness of this analysis hinges on how the resulting data is documented and shared. The SAE J2623-2018 standard defines a…
SAE J1058 (2024) is the definitive recommended practice for specifying thickness of uncoated and coated hot-rolled and cold-rolled steel sheet and strip. It provides a structured series of preferred thicknesses and tolerances, ensuring consistency across designs and supply chains, especially…
Consistent sign conventions are essential for comparing crash test results across different facilities. SAE J1733 defines standardized coordinate systems and recorded output polarities for transducers used in crash testing, including acceleration, angular rate, displacement, and load measurements. This information report…
Acoustical test results for standardized SAE and ASTM test procedures, as well as non-standardized vehicle test procedures, can be presented in a number of formats and scalings, making comparison(s) of results difficult in many cases. This article examines SAE J2629-2015,…
SAE J2236-2010 defines a robust test method for establishing the continuous upper temperature resistance (CUTR) of thermoplastic elastomers and thermoset rubbers. By measuring the retention of elongation and tensile strength after extended hot air aging, the standard helps engineers qualify…
The SAE J1222-2024 standard provides minimum requirements and performance criteria for devices designed to prevent runaway snowmobiles caused by malfunctions in the speed control system. This revision combines start and unmanned operation testing, updates terminology to accommodate new technologies, and…
SAE J496-2004, now cancelled and superseded by ASME B18.82, defined the requirements for coiled and slotted spring pins. While the standard is obsolete, its specifications still appear in legacy designs and industrial references. Understanding these requirements helps engineers correctly interpret…
Stainless steel and bimetal are popular choices for exterior automotive bright trim, offering a blend of aesthetics and durability. However, without careful design and material choices, these components can suffer from crevice corrosion, galvanic corrosion, and surface contamination. This article…
Low carbon cast steel shot is a critical media for shot peening and blast cleaning operations. SAE J2175 establishes the material and performance requirements to ensure consistent, reliable results. This guide covers the key specification points for engineers and quality…
SAE J1776 (revised 2014) is a recommended practice that provides comprehensive guidance for evaluating and specifying hydraulic pumps and motors for marine vehicle applications. Originally focused on advanced surface craft and deep submersibles, the latest revision expands the scope to…
