  • Shelf life is the total period of time beginning with date of manufacture, cure, assembly, pack, or after inspection or test that an item may remain in the combined wholesale/retail storage systems and remain suitable for issue to and/or consumption by the end user
  • A shelf-life item is any item possessing deteriorative or unstable characteristics to the degree that a storage period must be assigned to assure the issuance of material that will perform satisfactorily in service” 3

The overarching NASA standard for fastener procurement, receiving inspection, and storage practices for all fasteners used for spaceflight hardware that are procured, received, tested, inventoried, or installed for space flight by a NASA Center, by a prime contractor, or by any other spaceflight hardware developer is NASA-STD6008: NASA FASTENER PROCUREMENT, RECEIVING INSPECTION, AND STORAGE PRACTICES FOR SPACEFLIGHT HARDWARE.

Summary

  • Fastener: An item such as a bolt (could be a tensile or shear bolt, shoulder bolt, screw, HiLok®, HiTigue®, or lockbolt), nut, nut plate or anchor nut, rivet, shear pin, helical or cylindrical insert, setscrew, washer, safety wire, cotter pin, etc., which joins or retains components or structural elements.
  • Selection and Procurement, Test Reports, Traceability, Audits and Storage, COTS, and Quality are all very important when working with fasteners

Summary

Static electricity is an electrical charge at rest. Electrostatic discharge is the transfer of charges between bodies at different potentials caused by direct contact or induced by a charged field.

The prime method of generating static is by rubbing or separating materials, commonly known as the Triboelectric Method. A triboelectric charge is defined as "an electrical charge generated by frictional movement, or separation of two surfaces".

Summary

Quality planning begins when top management of a company includes prevention as opposed to detection in its policy and objectives. Quality must include all properties of a product that contribute to customer satisfaction in terms of physical characteristics, durability, maintainability and reliability. To achieve quality objectives the management must provide an organization with resources for training, information gathering and data analysis. The effective use of statistical techniques must be emphasized.
