Component

A metallic material using in a brazing process to join two metals or metallized components.

Nondestructive ways to verify the operation and functions of a circuit; usually done multiple times "on the fly" at either startup or field usage stage. BIT is an integral capability of the mission equipment, which provides an onboard, automated test capability, consisting of software or hardware (or both) components, to detect, diagnose, or isolate product (system) failures. The fault detection and, possibly, isolation capability is used for periodic or continuous monitoring of a system's operational health, and for observation and, possibly, diagnosis as a prelude to maintenance action.

Radiation that converts impacted items wholly or partly into ions (electrically charged particles). The particulate radiation component includes all subatomic particles, such as protons, neutrons, electrons, atomic nuclei stripped of orbital electrons, mesons, etc.

A list of vendors of components, subsystems, or systems that meet specified criteria and/or have an acceptable performance record when used in the organization’s products or systems. This subset of potential vendors is used to minimize selecting unacceptable vendor products and to minimize contractual agreements with suppliers.

The analysis of parts and components to predict the rate at which an item fails. In parts count prediction, the expected or known failure rates for all components within an item are tallied to estimate the item’s overall failure rate. (However, this method is proven to be very inaccurate at estimating the actual field failure rate.)
