NAVMAT P-9492, NAVY MANUFACTURING SCREENING PROGRAM: DECREASED CORPORATE COSTS INCREASE FLEET READINESS (MAY 1979)

NAVMAT P-9492, NAVY MANUFACTURING SCREENING PROGRAM: DECREASED CORPORATE COSTS INCREASE FLEET READINESS (MAY 1979)., This publication provides guidance concerning the use of temperature cycling and random vibration as manufacturing screens for defects in both parts and workmanship. The requirements for such screens are called out in Navy instructions and reflected in contract requirements. Section 2.0 on temperature cycling is derived from a Martin Marietta report for the National Aeronautics and Space Administration on industry experience in assuring long-life hardware. Section 3.0 on random vibration has been prepared by the Grumman Aerospace Corporation under the direction of the Naval Electronic Systems Command. It summarizes the experience of Grumman and others supporting the NASA manned space program. Grumman recently has devised a technique to simulate random vibration at low cost without a sacrifice in effectiveness as a manufacturing defect screen. This technique is included as an appendix to this publication. Section 4.0 contains the minimum recommended thermal cycling and random vibration manufacturing screens to be used in the production of Navy equipment.
