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.
In the paint and coating industries, paint adhesion testing is often used to determine if the paint or coating will adhere properly to the substrates to which they are applied. Several tests measure the resistance of paints and coatings from substrates: cross-cut test, scrape adhesion, pull-off test , and others.

The hair perforation test, also known as an in vitro hair perforation test, is a laboratory test used to help distinguish the isolates of dermatophytes, such as Trichophyton mentagrophytes and its variants. [1] The test is performed by placing an organism into a Petri dish containing water, yeast extract, and hair. After incubation for 4 week ...

Shear testing is the alternative method to determine the strength a bond can withstand. Various variants of shear testing exist. Like with pull testing, the objective is to recreate the failure mode of interest in the test. If that is not possible, the operator should focus on putting the highest possible load on the bond. [18]
