Reliability sequential testing3/25/2023 The failure rate varies in a predictable manner over the life of the product and can be considered as occurring in three different periods of the life of the product. MIBF does not include or represent any wear-out phenomena, only random failures. Do not confuse MIBF with life of an item. This is the average time that the product will operate before a failure will occur. This concept is called the "mean time between failures" (MTBF). A concept related to failure rate (its mathematical inverse) is often used to more clearly specify or measure reliability. In all manufactured products there is a measure of reliability called "failure rate." This can be the number of malfunctions occurring per unit time for continuously operating products or the number of malfunctions after a number of uses for on-off products. Not performing satisfactorily implies failure of one or more components of the product. "Probability" means, in the mathematical sense, a number between 0 and 1 (with 1 representing 100%) indicating the likelihood of occurrence. The reliability of a manufactured product is defined as the probability that it will perform satisfactorily for a specified period of time under stated use conditions. Now in the area of medical devices with their increasing sophistication and reliance on electronics, material science, and other space age technologies, the considerations of reliability are part of FDA's concerns in reference to their safety and effectiveness. With the Apollo Man-On-The-Moon project, reliability became a central consideration in the design, for humanitarian considerations as well as for national prestige. With each launch costing $6 million, it was obvious that there is financial importance to reliability. The early Vanguard satellite had a probability of mission success of only 64%. Similar experience by the other services made it evident that reliability must be designed into their field equipment. ITG SUBJECT: RELIABILITY OF MANUFACTURED PRODUCTSÄuring World War II, a Navy survey revealed that its electronics equipment was not operative 30% of the time.
