Product lifetimes can be modelled using extant data from surveys with the application of probability and other statistical concepts (e.g. distributions). [12] [22] One of the earliest attempts to estimate product lifetimes was undertaken by Pennock and Jaeger [23] who utilised actuarial methods to measure the Service life of household goods for ...
Front page of a floppy disk controller data sheet (1979) A datasheet, data sheet, or spec sheet is a document that summarizes the performance and other characteristics of a product, machine, component (e.g., an electronic component), material, subsystem (e.g., a power supply), or software in sufficient detail that allows a buyer to understand what the product is and a design engineer to ...
High-temperature operating life (HTOL) is a reliability test applied to integrated circuits (ICs) to determine their intrinsic reliability. This test stresses the IC at an elevated temperature, high voltage and dynamic operation for a predefined period of time. The IC is usually monitored under stress and tested at intermediate intervals.

The design life of a component or product is the period of time during which the item is expected by its designers to work within its specified parameters; in other words, the life expectancy of the item. It is not always the actual length of time between placement into service of a single item and that item's onset of wearout.
Amortization is the acquisition cost minus the residual value of an asset, calculated in a systematic manner over an asset's useful economic life. Depreciation is a corresponding concept for tangible assets. Methodologies for allocating amortization to each accounting period are generally the same as those for depreciation.
Electrical equipment part of the distribution system in a large building. Electrical equipment includes any machine powered by electricity. It usually consists of an enclosure, a variety of electrical components, and often a power switch.
