The purpose of this Specification is to establish and implement the manufacturing and test requirements and applications guidelines for normally closed (NC) parent metal shear-section valves. The Specification is a guide for design engineers to develop more detailed requirements for specific pyrovalve applications. Adherence to these requirements will reliably prevent NC parent metal valve leakage or other failure-induced release of hazardous fluids (liquids or gases) from National Aeronautics and Space Administration (NASA) payloads on Expendable Launch Vehicles (ELVs). This Specification does not address NC parent metal valve sizing, pressure drop, and other requirements.
