Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document

    7、shall be addressed to: Commander, US Army Tank-Automotive and Armaments Command Research and Development Center, ATTN: AMSTA-AR-QAW-E, Picatinny Arsenal, NJ 07806-5000, by using the self addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or b

    8、y letter. Comments should be forwarded through the designated Reviewing Activity listed for each Service in 4.9. 3. This standard establishes specific design safety criteria for fuzes. It applies primarily to the safety and arming functions performed by fuzes for use with munitions. The safety and a

    9、rming requirements specified herein are mandatory fundamental elements of design, engineering, production and procurement of fuzes. Fuzes shall provide safety that is consistent with assembly, handling, storage, transportation, use, and disposal. 4. Munition fuzes historically have utilized sensitiv

    10、e explosive elements whose output has been physically interrupted until arming. Control of the arming process in these fuzes was accomplished by mechanical means. The advent and rapid advancement in solid state electronics has furnished alternatives for fuze safety design. In recent years, advances

    11、in explosive initiation elements have provided an option for eliminating the need for physical interruption of the explosive train. The application of these technology advances is addressed in the Current revision to these standards. Supersedes page ii of 10 July 1998 II Provided by IHSNot for Resal

A physical system designed to sense a target or respond to one or more prescribed conditions, such

    35、in the fuze to prevent arming and functioning of the fuze until a valid launch environment has been sensed and the arming delay has been achieved. 3.21 Independent safety feature. A safety feature is independent if its integrity is not affected by the function or malfunction of other safety features

    36、. 3.22 Initiator.

    38、d to accomplish the end result in the munition; e.g., bursting a casing to produce blast and fragmentation, splitting a canister to dispense submunitions, or producing other effects for which it may be designed. Main charge explosives are compounds or formulations such as TNT or Composition B, which

    39、 are used as the final charge in any explosive application.

The following general requirements apply to all fuzes and fuze components within the scope of this document. 4.2 Fuze safe system In order to preclude unintended fuze arming, the fuz

    46、e safety system shall: a. not initiate the arming sequence except as a consequence of an intentional launch. b. not be susceptible to common-mode failures. c. not contain any single-point failure mode prior to or at the initiation of the arming cycle. d. reduce to a minimum single-point failure mode

    47、s during the arming cycle. The time window associated with these single-point failures shall be reduced to a minimum and shall exist only at or near the expiration of the intended arming delay. In addition, the fuze design shall prohibit premature fuze arming or functioning if any or all electrical

    48、safety or energy control features fail in any given state or credible mode. These failure modes include both random and induced failures which occur prior to, during, or after application of electrical power to the fuze. 4.2.1 Safety redundancy. The safety system of fuzes shall contain at least two

    49、independent safety features, each of which shall prevent unintentional arming of the fuze. The stimuli enabling a minimum of two safety features shall be derived from different environments. Utilization in the fuze design of environments and levels of environmental stimuli to which the fuze may be exposed prior to initiation of the launch cycle shall be avoided.
