A pull-off test, also called stud pull test, is a type of test in which an adhesive connection is made between a stud and a carrier (or object to be tested) by using a glue, possibly an epoxy or polyester resin, that is stronger than the bond that needs to be tested.
The cross-cut test is a method for determining the resistance of paints and coatings to separation from substrates by utilizing a tool to cut a right-angle lattice pattern into the coating, penetrating to the substrate. A quick pass/fail test can be accomplished through this method.
The MIL-STD-883 standard establishes uniform methods, controls, and procedures for testing microelectronic devices suitable for use within military and aerospace electronic systems including basic environmental tests to determine resistance to deleterious effects of natural elements and conditions surrounding military and space operations; mechanical and electrical tests; workmanship and ...
Most common are "jerk testing" by modified drop test procedures or use of the constant pull rates of a universal testing machine. Other procedures use a static force by hanging a heavily loaded package for an extended time or even using a centrifuge .
USB Tweezers performing cold bump pull (CPB) on a bond tester. Measuring bond strength by pull testing is often the best way to get the failure mode in which you are interested. Additionally, and unlike a shear test, as the bond separates, the fracture surfaces are pulled away from each other, cleanly enabling accurate failure mode analysis.
The College Football Playoff releases the fifth top 25 rankings of the season Tuesday. Here’s what to know and how to watch the show.
Spicy Chick-Fil-A Chick-n-Strips. For those who crave a kick of heat, Chick-fil-A’s Spicy Chick-n-Strips were a standout hit. Chicken breast strips seasoned with a spicy blend of peppers quickly ...
(top-bottom) The point forces, shear stresses, and moments acting on an asymmetric four point bend test sample. Asymmetric four-point bending (AFPB) may be chosen to measure interlaminar shear strength over other procedures for a variety of reasons, including specimen machinability, test reproducibility, and equipment availability.
