ISO 26262 Fault Metrics Intro

WebAug 1, 2011 · Failure rate can be defined as the anticipated number of times that an item fails in a specified period of time. It is a calculated value that provides a measure of reliability for a product. This value is normally expressed as failures per million hours, but can also be expressed as a FIT (failures in time) rate or failures per billion hours.
