This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist.This document presents the technical aspects for remotely actuated, umbilical systems quick-disconnect couplings. These umbilical systems couplings are used in connecting launch-complex servicing lines to a vehicle for the transfer of liquid and gas compounds and mixtures. This Aerospace Recommended Practice includes the following areas: basis for system requirements; selection of materials coupled with hazards and safety; configuration of design; system operations; and evaluation testing.
