The molecular mechanisms by which materials can adhere to one another have not been determined unambiguously. To date, no one has been able to predict reliably the strength of an adhesive joint based purely on the properties of the adhesives and adherends. Rather, to determine the strength of a joint, one must resort to testing. As will hopefully be made clear in this chapter, testing is not always as straightforward as it might appear superficially. Testing is, however, an important aspect of adhesive science and technology. Tests are conducted for a wide variety of purposes. There are a large number of different standard adhesive tests available to the technologist, engineer, or scientist, depending on his or her goals. It is essential not only that the proper test be selected (or designed) and that care be exercised in conducting the test, but also that the results be interpreted properly. The latter aspect often requires considerable background and insight.
