MIL-STD-1576

Abstract

The purpose of this document is to insure the safety of personnel, launch site facilities, and space vehicles from the hazards resulting from electroexplosive subsystem unintentional initiation or failure to fire. The requirements and test methods contained in this document are not intended to insure all electroexplosive subsystem performance requirements except in those cases where failure to perform would create a hazard to the items listed above. The electroexplosive subsystem is composed of all components from the power source to, and including, the EED (electroexplosive device); Safe and Arm devices, Arm/Disarm switches, relays and all electrical wiring used to monitor, control, arm and fire ordnance are specifically included. This Standard applies to all space vehicle systems (e.g., launch vehicles, upper stages, boosters, payloads, and related systems using EEDs). <br>The test methods described herein have been prepared to: <br>a. Specify laboratory test conditions for electroexplosive subsystems and components which will produce test results that are equivalent to those which would be experienced in the actual operational environment and which will permit reproducibility of test results. <br>b. Describe all test methods for electroexplosive subsystems and components needed to ensure compliance with the requirements of the specification. <br>c. Provide Test Method 2208 as a Standard method for RF dudding evaluation if required by the procuring activity. <br>Revisions of each test method shall be indicated by a revision number following the method number. For example, the first revision of Test Method 1101 would be 1101.1, the second revision would be 1101.2, et cetera. <br>This Standard is applicable to the entire electroexplosive subsystem life cycle, up to the time when the electroexplosive subsystem no longer presents a hazard to personnel, launch site facilities and manned or reusable space systems. This Standard also applies to expendable launch vehicles which present these types of hazards. <br>a. This Standard is intended to be used by procuring activities for establishing all of the electroexplosive subsystem safety requirements to be included in specifications for the design and development of new hardware for new or old space systems. <br>b. This Standard is intended to be used by procuring activities and government safety organization for a safety evaluation of previously used hardware on new space systems as well as for a safety evaluation of new hardware on new or old space systems. <br>c. This Standard is not intended to be used by procuring activities for establishing all of the performance (as opposed to safety) requirements to be included in specifications for the design and development of new ordnance system hardware for new or old space systems, but it can be used to establish many electroexplosive subsystem performance requirements. This Standard does not address elements of explosive trains which exist beyond an EED, except for S&A configurations. <br>d. This Standard is intended to be used by space system procuring activities in lieu of MIL-STD-1512, "Electroexplosive Subsystems, Electrically Initiated, Design Requirements and Test Methods." MIL-STD-1512 contains requirements applicable to non-space systems, such as aircraft weaponry, and has not been superceded by this Standard. <br>When the scope and magnitude of a program does not warrant imposition of all the requirements specified herein, the procuring activity shall obtain approval from the appropriate government safety organization(s) and shall specify to the contractor the minimum acceptable program requirements.
