Qualification Test of Handle Strap, P/N 9381751, Manufactured by Panduit Corporation for 81-mm Mortar Ammunition Fiber Container.

摘要

This report details the tests conducted on the plastic handle straps, drawing 9381751, needed to assemble the plastic handles to fiber (tube) containers used to pack the 81 mm mortar ammunition. The strength of straps received from Thomas and Betts Corporation, the approved source of supply stated on the drawing, was compared with those by Panduit Corporation, a candidate supplier. Test runs stressed the strap's material and locking device to failure after 2 hr of temperature conditioning at -50 F, +70 F, and +160 F. The test results indicated that the strength of Panduit candidate strap samples was much less than that of the Thomas Betts' product, therefore, not acceptable for use to pack the 81 mm mortar ammunition in their fiber containers.
