The space qualification has to be conducted by a high level of screening to ensure the design margin of devices, materials, manufacturing processes, units, modules, and subsystem or system. The space qualification according to traditional test standards proposed by US military, NASA and ESA involve high cost and tight schedule due to their conservative requirements. It is necessary to develop a space qualification guideline that is cost-efficient and schedule-optimized for the development of domestic satellites. In this study, as a basic research to develop the space qualification guideline, the articles related to space qualification in test standards document released from military and space agency have been investigated. We are planning to utilize the results as a basic database for establishing the independent tailored space qualification guideline.

Since the late 1990's, FAA, NASA and the aerospace industry have worked together to develop the sharing system of the composite material qualification databases which were obtained through the standardized fabrication and testing procedures. The result was what is now known as the AGATE(Advanced General Aviation Transport Experiments) or NCAMP(National Center for Advanced Materials Performance) methodology, a more cost-effective concept that shifts the major responsibility for qualification and testing from the aircraft manufacturer to the material supplier. The properties of composite materials are largely dependent on the testing as well as the raw material properties and the manufacturing process including the process control parameters. Thus it is important in the composite material qualification to comply with the standardized testing procedures. In this paper, I will describe the standardized witness methodologies of certification engineers to reduce the effect of testing variability within the qualification data.
