SAE J4002 defines the H-Point Machine (HPM-II) specifications and procedures for determining the H-point and auditing vehicle seats. This standard consolidates HPM-II/ASPECT manikin auditing and calibration into one document, providing a consistent method for establishing interior reference points, validating seat…

The SAE J387 standard has been a cornerstone of automotive lighting documentation since 1969. The 2014 revision updates and clarifies definitions used across SAE documents, ensuring engineers, designers, and compliance professionals share a common language. This article explores the key…

For engineers working with global teams, dual dimensioning – including both inch-pound and SI metric units on the same drawing – is essential. SAE J390 (revised 1999) provides a uniform method for combining these units while maintaining functional interchangeability. This…

SAE J391 is a recommended practice that defines how particle size should be specified for materials used in surface enhancement processes such as abrasive blasting. The standard establishes a consistent method for designating particle sizes based on sieve analysis and…

SAE J384 is a stabilized recommended practice that specifies performance requirements and test procedures for the strength and location of seat belt assembly anchorages. This standard applies to anchorages attached to vehicle body structure or seat assemblies and is essential…

This standard establishes essential criteria for pelvic restraint systems—including seat belts, anchorages, and fastening elements—used in off-road work machines. The 2022 revision incorporates updated ISO references, specific retractor and latch plate requirements, and new center of gravity testing for heavy…

Hardness testing is a cornerstone of quality control for brake linings, ensuring consistency in formulation and processing. The Gogan hardness test (SAE J379-2017) is a nondestructive method that measures the compression of the lining material under load. Unlike Rockwell hardness,…

1. Purpose and Scope SAE J380-2017 establishes a uniform procedure for determining the specific gravity of brake friction materials. This nondestructive test serves as a quality control check to ensure consistency in formulation and processing. It is important to note…

This article summarizes the design recommendations from SAE J383-2022 for motor vehicle seat belt anchorages. The standard provides guidance on anchorage locations to properly transfer occupant restraint forces to the strongest parts of the human anatomy. While stabilized, it remains…

SAE J376, originally issued in 1968 and revised in 1985, was reaffirmed in 2019 to align with the SAE five-year review cycle. This recommended practice establishes guidelines for load indicating devices used in lifting crane service, focusing on performance, accuracy,…
