1、AMSC N/A FSC 8140 INCH-POUND MIL-STD-1660A 7 August 2008 SUPERSEDING MIL-STD-1660 8 April 1977 DEPARTMENT OF DEFENSE DESIGN CRITERIA STANDARD AMMUNITION UNIT LOADS Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-STD-1660A ii FOREWORD 1. This stan
2、dard is approved for use by all Departments and Agencies of the Department of Defense. 2. This standard establishes minimum design and evaluation procedures to be applied throughout the Department of Defense to unit loads of ammunition. It provides guidelines covering unit loads for ammunition desig
3、ned to establish reliability, safety, and compatibility with handling equipment most commonly found in the distribution system. 3. When ammunition items, packaged or unpackaged, are moved from one place to another, they are usually combined into a larger assemblage which can be easily and safely han
4、dled by mechanized equipment; e.g., a forklift truck. This assemblage is called a unit load. 4. The ammunition logistics system of the Department of Defense is based on distribution in unit loads unless the item, as packaged, is too large or too heavy to be so assembled. A unit load may be stored fo
5、r prolonged periods before it is needed. It may be shipped by truck, rail, ship, or aircraft. Depending upon the particular operations of the consuming combatant unit, the unit load must withstand the rigors of over the beach handling, local transport and handling over rough terrain, or delivery by
6、external or internal carriage by helicopter under the threat of enemy action, or by transfer-at-sea, or by combinations of these methods, at any time and under poor weather conditions. In addition to possible adverse effects on the reliability of the ammunition, failures of unit loads can lead to de
7、ath or injury from falling heavy objects or from disastrous explosion. Because of these factors, a detailed design must be prepared, tested, and documented showing how the ammunition is to be assembled into a unit load, which will be safe and efficient to handle, ship, store, and deliver to the comb
8、atant unit. 5. This is a mandatory standard for use by DoD ammunition design activities and when applicable is to be invoked in specifications, purchase descriptions, and/or contracts when such design service is to be procured. It applies to ammunition terms as prepared for shipment and not necessar
9、ily to metal parts, bulk, explosives, and other components. 6. Comments, suggestions, or questions on this document should be addressed to Commanding Officer, Naval Surface Warfare Center, Indian Head Division, Detachment Earle, Code E421, Colts Neck, NJ 07722 or emailed to CommandStandardsnavy.mil
