Processing methods durability considerations

The uncertainty of a measurement is always a very important consideration but it is especially so with durability tests. In addition to the basic physical test methods, there are the complications of exposure conditions, tests spanning long times and the process of extrapolating results to make predictions. The combination of these factors will inevitably lead to large uncertainties that can very easily be of such a magnitude that any conclusions are meaningless. Terms used to describe precision include repeatability, which refers to within laboratory variation and reproducibility, which refers to variation between laboratories. [Pg.134]

Abstract The use of surface treatments to optimize adhesion has been well established. In this chapter, the main treatment methods for metals and polymers will be considered in terms of how such processes are carried out and their influence on surface physical and chemical properties. Consideration has been given to a range of treatments from simple degrease options to the more highly complex multistage processes. An attempt has been made to relate the changes in physicochemical properties to adhesion performance, and, where relevant durability. [Pg.120]
