Which term describes an error or defect?

The term that describes an error or defect is "Fehler." This word directly translates to "error" or "defect" in German and is commonly used in various contexts, including engineering, manufacturing, and technical fields, to refer to any shortcoming or issue in a process, product, or system that does not meet established standards or expectations.

The other terms listed do not accurately convey the idea of an error or defect. For example, "Kleberauflösen" refers to the process of adhesive detachment, which is more specific to material adhesion than a general defect. "Verzerrung" translates to "distortion," which indicates a change in shape or structure rather than a defect per se. Lastly, "Reibkorrosion" means "friction corrosion," describing a specific type of wear due to friction rather than indicating a broad error or defect. Thus, "Fehler" is the most appropriate term to capture the essence of an error or defect in this context.
