38 Quality Assurance and Reliability

Includes approaches to, and methods for reliability analysis and control, quality control, inspection, maintainability, and standardization.

Definition

Quality Assurance – A system of activities whose purpose is to provide assurance and show evidence that the overall quality control task is in fact being done effectively. The system involves a continuing evaluation of the adequacy and effectiveness of the overall quality control program with a view to having corrective measures initiated where necessary. AGARD Multilingual Aeronautical Dictionary, 1980.

Reliability – Of a piece of equipment or a system, the probability of specified performance for a given period of time when used in the specified manner. NASA Thesaurus, Washington, DC: National Aeronautics and Space Administration. Dictionary of Technical Terms for Aerospace Use. Wm. H. Allen, ed., 1965. NASA SP-7.

NASA Interest

Exhaustive Interest : Quality control, quality assurance, and reliability theories, procedures, and practices specifically applicable to aircraft, space vehicles, launch vehicles, supporting facilities, other aerospace applications, and related equipment.

Selective Interest : Quality control, quality assurance, and reliability theories, procedures, and practices specifically concerned with developments and techniques for nonaerospace oriented activities that may be unusual or of use within the aerospace effort.
