Description / Abstract: FORD FLTM BA 157-01, 2006 Edition, May 25, 2006 - SELF-PIERCE RIVETING SCHEDULE DEVELOPMENT ACCEPTANCE TEST FOR ALUMINUM UNCOATED AND COATED LOW CARBON STEEL SHEET

Application

This procedure defines the self-pierce riveting acceptance test for rivet schedule development for aluminum, uncoated and coated low carbon steel sheet. All such sheet material must pass minimum performance testing. Consult the appropriate Engineering Material Specification for material exceptions. Testing confirms that the correct rivet and die combination were used to satisfactorily join a given gauge of sheet metal together. Cross sections of the rivet joint must be evaluated to insure a robust rivet joint. After the correct tooling has been identified lap-shear and T-peel samples are built. Initial testing requires a sample size of 30 each for the strength tests. Samples are pulled on a tensile test machine.
