MIL-STD-1660 Test of Unitization Procedure 19-48-4042A/9-20 PM1001, PA37 Containers and External Bundling Strap

The U.S. Army Defense Ammunition Center and School USADACS has previously tested the PA37 container unitizations using various dunnage methods. Unitization Procedure 19-48-4042A9-20 PM1001 shows the top dunnage assembly covering the unit bundling strap afer the charges are palletized, making it difficult to retighten after the tiedown strap stare added. The engineering change proposal ECP submitted to the U.S. Army Armament, Munitions and Chemical Command AMCCOM, SMCAR-ESK, by Indiana Army Ammunition Plant INAAP proposes the bundling strap be placed over the top dunnage assembly for easier retightening access. To verify this unitization modification, a test load was fabricated and tested at USADACS in accordance with MIL-STD-1660 testing requirements. As a result of this testing, the external bundling strap maintained a satisfactory unitization.
