Abstract: 
Depending on their application, sealants in service joints are exposed to different combinations of individual degradation factors. These degradation factors can attack a sealed joint on three fronts: the sealant itself, the sealant-to-substrate interface, and the substrate. This chapter suggests a classification scheme for the various degradation factors that act on a sealed joint.

Two main classes of degradation factors are proposed: environmental factors and service factors. The environmental factors are then further classified into weathering factors and biological factors. Service factors are further classified as design, installation and use factors. Service and environmental factors act simultaneously on the sealed joint, often displaying synergistic effects. Thus, the service factors augment and modulate the effects of the environmental factors.
