kestoiän
Kestoiän is a term used in reliability engineering and product labeling to denote the expected service life of a product or component. It refers to the length of time during which the item is expected to operate within defined performance and safety standards under normal use before it reaches a specified failure threshold or becomes unsuitable for use. Kestoiän is influenced by design, materials, manufacturing tolerances, operating environment, and maintenance, and it is typically published or inferred from testing data and historical performance.
Estimation of kestoiän relies on life data gathered through testing and field experience. Methods include accelerated
Kestoiän is distinct from shelf life, which concerns the duration a product can be stored without use,
Limitations exist: kestoiän is an estimate based on models and representative usage; real-world results vary with
