13042072A - Detonating Cord Drawing.PDF

This is an engineering drawing for a detonating cord assembly. The document is a technical specification sheet prepared by the U.S. Army Armament Research, Development and Engineering Center (ARDEC) at Picatinny Arsenal in New Jersey, dated December 6, 2025.

The drawing depicts a cylindrical detonating cord wound on a spool with a plastic jacket and textile counterwrap around a PETN core. The assembly includes detailed notes specifying compliance with MIL-DTL-17124 for detonating cord specifications and MIL-F-387 for the detonating cord spool construction. Key specifications include detonating velocity requirements (Type I Class P with 3,800 meters per second minimum and Type I Class PI with 6,300 meters per second), thermoplastic resin coating per ASTM D3911 standards, and color conformance per TED-STD-335/351(D). The drawing contains eight numbered notes addressing cord specifications, spool applicability, detonating velocity requirements, inter-connector cable specifications, and manufacturing tolerances. The document is labeled as Revision A with an engineering approval dated December 6, 2025, and includes a parts table reference, mechanical properties data table, and application field designating it as a next assembly used on equipment. The drawing is sheet 1 of 2 in the document set.
