Mechanical Impact Test definition
Mechanical Impact Test. A test used to determine the propensity of a material to ignite when subjected to an impact by a free-falling weight. The MSFC Ambient and High-Pressure Mechanical Impact testers use a plummet to impact a disk of the sample material which is immersed in liquid or gaseous oxygen. Metrology: Calibrated measurement or characterization of the fine dimensions, shape or surface roughness of precision manufactured hardware or optical components (lenses, mirrors and other specialized optics). Typically, government furnished equipment is provided for such tasks. National Center for Advanced Manufacturing (NCAM): Located within Materials and Processes Laboratory, NCAM addresses the manufacturing requirements of space transportation systems. Through NCAM, partnerships between National Aeronautics and Space Administration (NASA), other government agencies, industry, and academia are formed that leverage assets and successfully meet the requirements of future aerospace systems-- systems that will ultimately provide safe and low-cost access to space. Organizational Issuances (OI): Documents that provide procedures, instructions, etc., for internal use within an organization. OI’s include Organizational Work Instructions (OWI’s), procedures, plans, etc. Organizational Work Instructions (OWI): Documents that provide detailed instructions stating how to perform specific ▇▇▇▇▇▇▇▇ Management System directed duties that apply to one or more ▇▇▇▇▇▇▇▇ Space Flight Center organizations, but not all. The OWI document type can be used when other document type designations do not apply.
