2、 Defense.1. SCOPE1.1 =. This specification covers the general requirements for design andestablishes uniform methods for testing cartridges used in cartridge actuateddevices. Cartridges designed as stores separation cartridges used in storesseparation equipment and single discrete units which are us
3、ed as electricinitiators that are not an integral part (see 6.4.2) of the cartridge design do notfall within the scope of this specification but do fall within the scope ofMIL-D-81303 and MIL-I-23659, respectively. For purposes of this specification, theterm cartridge includes any assembled unit con
4、taining an explosive, propellant, orpyrotechnic material either singly cr in any combination designed as the energysource for cartridge actuated devices. Laser initiated cartridges, 1inear shapedcharge, explosive energy transfer lines, devices with the cartridge(s) “sealed-in”(see 6.4.1) and their a
5、ssociated ballistic assemblies used in cartridge actuateddevice application shall fall within the scope of this specification. The purposeof the testing program is to determine performance, safety, soundness of mechanicaldesign, and resistance to environments encountered during storage, handl ing, a
6、ndservice use. Cartridges must be safe for handling and must not deteriorate to adegree which would render their performance or safety doubtful after beingsubjected to the testing program of this specification.Beneficial comments (recommendations, additions, deletions) and any pertinentdata which ma

This type of release is requiredfor admission of the cartridges into the naval supply system as a fully documentedcart
12、ridge (see 3.9). For requirements see 3.16.2.Type 111 BSpecial release to service (documented by a source control drawing), If thedata required for a type 111 A release are not available, such as proprietaryrights and patents, then a type 111 B release to service for Fleet use is opermissible. For r
13、equirements for a type III B release see 3.16,2. Fordocumentation requirements for a type III B release see 3,9.Type IVUse of approved cartridge in a new application, If a cartridge has previouslybeen granted a type III A or type 111 B release and is to be used in a newapplication, type I release is
