2. Pull off test - Wikipedia

   en.wikipedia.org/wiki/Pull_off_test

   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.

3. Junker test - Wikipedia

   en.wikipedia.org/wiki/Junker_test

   A Junker test is a mechanical test to determine the point at which a bolted joint loses its preload when subjected to shear loading caused by transverse vibration.. Design engineers apply the Junker test to determine the point at which fastener securing elements – such as lock nuts, wedges and lock washers – fail when subjected to vibration.

4. Proof test - Wikipedia

   en.wikipedia.org/wiki/Proof_test

   A proof test is a form of stress test to demonstrate the fitness of a load-bearing or impact-experiencing structure. An individual proof test may apply only to the unit tested, or to its design in general for mass-produced items. Such a structure is often subjected to loads above those expected in actual use, demonstrating safety and design margin.

   Illinois Tool Works Inc. or ITW is an American Fortune 500 [2] company that produces engineered fasteners and components, equipment and consumable systems, and specialty products. It was founded in 1912 by Byron L. Smith and has built its growth on a "small-wins strategy" based on decentralization, simplicity, customer-focused innovation, and ...

6. Powder-actuated tool - Wikipedia

   en.wikipedia.org/wiki/Powder-actuated_tool

   The propellant acts on the piston, which then drives the fastener into the substrate. The piston is analogous to the bolt of a captive bolt pistol. A tool is considered low velocity if the average test velocity of the fastener is not in excess of 300 ft/s (91 m/s) with no single test having a velocity of over 108 m/s (350 ft/s). [1]

7. Preload (engineering) - Wikipedia

   en.wikipedia.org/wiki/Preload_(engineering)

   It is also used in testing a specimen, for a process where the crosshead moves to load the specimen to a specified value before a test starts. Data is not captured during the preload segment. When tensile specimens are initially placed into testing grips, they can be subjected to small compressive forces. These forces can cause specimens to ...
