scope:

a. This document provides guidance on the design of distributed fuzing systems that utilize low voltage electrical signals to properly arm the fuze for subsequent detonation. The primary purpose of this document is to describe acceptable architectures and signal format, addressing safety design and basic suitability for service use. This document is applicable to distributed in-line fuzing systems; however, the concepts may apply to out-of-line fuzing systems that remotely process the arming environments. Additional architectures and signal formats, beyond those presented in this document, may be acceptable based on unique program specifications to further support suitability for service use.

b. This document applies to fuzes, Safe and Arm devices (S&As), and Ignition Safety Devices (ISDs). (NOTE: The term "fuze" as used throughout this document is interchangeable with the terms "S&A" and "ISD".) Exclusions include nuclear weapon systems and associated trainers, flares and signals dispensed by hand-held devices, and pyrotechnic countermeasure devices. This document does not replace the basic fuze or ISD safety requirements of MIL-STD-1316, MIL-STD-1901, or MIL-STD-1911. When feasible, every effort should be made to collocate safety features in accordance with MIL-STD-1316. When operational requirements preclude collocation of safety features, use of an acceptable low voltage command-arm (LVCA) architecture may be used if such architecture is agreed upon by the Service Safety Authorities (SSA) and acceptable rationale is provided.

c. This document has been developed by the DoD Fuze Engineering Standardization Working Group (DoD FESWG) for use by the Army Fuze Safety Review Board (AFSRB), the Army Ignition System Safety Review Board (ISSRB), the Air Force Nonnuclear Munitions Safety Board (NNMSB), and the Navy Fuze and Initiation System Technical Review Panel (FISTRP).

d. The SSA will review fuze, S&A, and ISD designs for acceptability using the guidance contained herein. Individual services may issue regulations or instructions which impose additional design safety criteria. Each program is encouraged to engage the appropriate SSA to determine the applicability of the guidance as well as any pertinent conditions and/or additional requirements. Continued dialogue should occur with the SSA as the design matures to facilitate the safety certification/concurrence process.
