(redirected from MTTF)
Also found in: Dictionary, Thesaurus, Medical, Legal, Acronyms, Encyclopedia.


the extent to which a product fulfils its function over a period of time.

The reliability of a product depends upon its design characteristics, the quality of materials and components embodied within it and the care with which it is made and assembled.

A product's reliability is an important part of its performance in use and thus affects the appeal of the product to customers and the likelihood of their buying it. See BRAND LOYALTY. See QUALITY CONTROL, FAILURE RATE CURVE, PARALLEL SYSTEM.

With the result that change into : Instrument MTTF C L RR [lambda] O1LV1O24 224719 4 l 4 4.45 x [10.sup.-10] Based on the analysis to the existing SIS SIL in ammonia refrigerant compressor 105 J produces NO SIL value.
Both PFR and NP.sub.est_fail could be extremely valuable in predicting how MTTF changes over time.
Reference [27] established an optimal ADT procedure to minimize the asymptotic variance of the MLE of the MTTF of a product, given a budget for the total cost.
* Mean time to failure (MTTF); purely used for one shot items which can form parts of a product or a product in its own right.
Two kinds of software quality measures are in general use: estimates of the number of errors remaining in a program, and estimates of the mean time to failure (MTTF) of a system.
The golden rule of an experiment states that "the duration of an experiment is not supposed to exceed the lifetime of the experimentalist." It is impractical and uneconomical to wait for failures, when the mean-time-to-failure (MTTF) for a typical electronics device today is on the order of hundreds of thousands of hours.
The MSAG TiWN gate is extremely robust (it survives a 900[degrees]C rapid thermal anneal temperature), which results in an MTTF of 100 years at a channel temperature of 150[degrees]C.
In a survey of well-debugged programs, MTTF ranging from 1.6 years to 5,000 years was reported[4].
