Specifications - SAE Mobilus
This SAE Information Report contains definitions for hydrogen fuel cell powered vehicle terminology. It is intended that this document be a resource for those writing other hydrogen fuel cell vehicle documents, specifically, Standards or Recommended Practices.
This document describes the assembly force guidelines for manually seated push-pins, clips, and similar retention devices. For the purpose of this document, the term “clip” is used to reference all retention devices addressed within this document. Applicable retention devices must have force exerted directly to the clip using the finger/thumb and are hand seated independent of other fasteners. For a retention device to be manually installed and seated independent of other retention devices, it must be seated fully without any interaction with an adjacent fastener (i.e., multiple PIA clips on the back of a hard trim panel). This standard applies to contact surfaces angled at 90 degrees (±10 degrees) and/or perpendicular from the direction of force insertion. Mechanically installed fasteners (screws, rivets, etc.) are not included in this document. This standard does not apply to extraction/retention forces. Refer to USCAR-44 for additional guidelines for clips attached to wire harnesses
A bolt-load retention (BLR) test is a practical test to determine the bolt load of a fastener joint with time and at given temperatures. There are three types of BLR tests described in this standard, namely general-purpose test, design-purpose test, and screening material test. A general-purpose BLR test may be used for screening materials, while a design-purpose BLR test is usually used to verify the BLR behavior of a specific joint. The screening material test is an example of the general-purpose test for typical automotive applications.
This standard outlines test methods and practices which can detect embrittlement of steel parts. It is a process control or referee verification test. The risk of embrittlement of steel is minimized by using best practices in the finishing/coating process. One such practice is described in SAE/USCAR-5, Avoidance of Hydrogen Embrittlement of Steel.
This standard provides a test method for determining the torque-tension relationship of a fastener finish as applied to a surrogate screw for the purpose of measuring the frictional characteristic of the fastener finish. The results obtained by this test shall be used as a process control attribute of the fastener finish and shall not be utilized for specific applications.
