Web1.15 Mean Time Between Failure. Mean time between failure (MTBF) is a prediction of the reliability of a product. Tests and statistical analysis of parts and components are performed to predict the rate at which a product will fail. It is one of the most common forms of reliability prediction and is usually based on an established analysis model. WebThis metric is often referred to as "mean time to failure" (MTTF) or "mean time before failure" (MTBF). Failure Rate: The number of failures per unit time that can be expected to occur for the product. Reliable Life (warranty time). The estimated time when the reliability will be equal to a specified goal.

WebMTBF = # of operational hours ÷ # of failures. For example, an asset may have been operational for 1,000 hours in a year. For that year, that asset broke down eight times. Therefore, the MTBF for that piece of equipment is 125 hours. To get an accurate measure of MTBF, you must collect data from the actual performance of the equipment.
