Overview of the Weight Loss Method This SAE Recommended Practice provides a gravimetric procedure for measuring fuel permeation at elevated temperatures through low-permeating hose or tubing of elastomeric or composite construction. The method is accurate to within approximately ±10% and…

Purpose of SAE J2654 The SAE J2654 standard defines a nondestructive test method for measuring the Rockwell hardness of brake linings. Hardness measurements serve as a quality control check to ensure consistency in formulation and processing. It is important to…

For naval architects, marine engineers, and procurement specialists, specifying the correct fastener is critical for reliability and safety. SAE J2656-2016 provides a standardized framework for inch-dimensioned set screws — including hexagon socket, square head, and slotted headless types — used…

SAE J2658-2013, a recommended practice for test methods of carbon and steel alloy tube conductor assemblies in fluid power systems, was officially cancelled in September 2013. It has been superseded by SAE J2551-2, part of a restructured three-part standard that…

SAE J265-2015, originally issued in 1971, established dimensional requirements for mounting and interchangeability of four specific fuel injector nozzle holder types used in diesel engines. The standard was officially cancelled in November 2015 and superseded by the international standard ISO…

SAE J2650-2021 establishes additional performance requirements for road illumination devices using LED sources, including low beam, high beam, front fog lamps, auxiliary high beam, and front cornering lamps. This recommended practice supplements device-specific SAE standards and specifies tests based on…

Automotive embedded systems must operate reliably under harsh conditions for years. SAE J2640-2008 provides a set of recommended practices covering interrupt management, timing consistency, watchdog usage, memory integrity, and microcontroller configuration. Developed with input from OEMs, suppliers, and industry consultants,…

Standardized testing of rubber materials exposed to automotive fluids is essential for ensuring long-term sealing performance. SAE J2643-2023 defines Standard Reference Elastomers (SREs) — precisely formulated and vulcanized rubber sheets used to characterize the effect of test liquids and service…

SAE J2646-2022 is a revised recommended practice that defines uniform test procedures for evaluating the air-conditioning (A/C) performance of on-highway heavy trucks, including those with day cabs, crew cabs, and sleeper compartments. This standard ensures consistent, repeatable test results through…

Why Standardized Filiform Corrosion Testing Matters Filiform corrosion can compromise the appearance and integrity of painted aluminum wheels and trim. Without a consistent test method, results vary between labs, raising costs and reducing confidence. SAE J2635:2025 addresses this by defining…
