General uses lot acceptance testing qualification and evaluation testing surveillance testing malfunction investigation product improvement testing integrity testing of spreader gun hardware. Examples of applications Velocities of selected shroud line attachments can be measured. Ignition delays, integrity of hardware, etc., can be measured. Test samples Test samples consist of the cartridges to be tested using the IHD, NSWC custom-built spreader gun simulator. Samples are receipt inspected for any physical damage, proper dimensions, and overall workmanship.
Leak testing is performed.
Samples are conditioned if necessary, then fixtured and tested. Special considerations Testing generally is limited to one fixture design. Measurements generally are limited to the ejection velocity and ignition delay of shroud line attachments. This information resides on a DOD interest computer.
