About this file
This document contains a vendor's exceptions and responses to technical requirements for a Request for Proposal (RFP) related to Shielded Mild Detonating Cords (SMDC). The vendor is requesting exceptions to several requirements in MIL-DTL-32154A and associated drawings, including first article testing, booster cup load, and test setup details. The vendor proposes alternative testing methods and equipment, citing continuous production history and safety concerns. The related federal contract opportunity is a solicitation (N0010423RK067) from the Department of the Navy Naval Supply Systems Command for SMDCs, with a limited drawing package available. The procurement is restricted to two vendors, Pacific Scientific Energetic Materials Company and Rockwell Collins, and a safety survey will be required.
