Academic enquiry into the product lifetimes of electrical and electronic equipment was undertaken in 2000 by Cooper and Mayers [21] who conducted household interviews and focus groups to establish the age at discard (actual product lifetime) and expected lifetimes for 17 products. Since this study, work has been undertaken by other academics ...
Given a component database calibrated with field failure data that is reasonably accurate, [1] the method can predict device level failure rate per failure mode, useful life, automatic diagnostic effectiveness, and latent fault test effectiveness for a given application.
Many organizations maintain internal databases of failure information on the devices or systems that they produce, which can be used to calculate failure rates for those devices or systems. For new devices or systems, the historical data for similar devices or systems can serve as a useful estimate. Government and commercial failure rate data
In the later life of the product, the failure rate increases due to wearout. Many electronic consumer product life cycles follow the bathtub curve. [ 1 ] It is difficult to know where a product is along the bathtub curve, or even if the bathtub curve is applicable to a certain product without large amounts of products in use and associated ...
IEC TR 60930 Guidelines for administrative, medical and nursing staff concerned with the safe use of medical electrical equipment and medical electrical systems IEC 60931 Shunt power capacitors of the non-self-healing type for a.c. systems having a rated voltage up to and including 1000 V
IAS 16 applies to property, plant and equipment (PPE). The standard itself defines PPE as "tangible items that are held for use in the production or supply of goods or services, for rental to others, or for administrative purposes; and are expected to be used during more than one [accounting] period."

Electrical machines are usually designed with an average temperature below the rated hot-spot temperature to allow for acceptable life. Insulation does not suddenly fail if the hot-spot temperature is reached, but useful operating life declines rapidly; a rule of thumb is a halving of life for every 10 °C temperature increase.
