This document establishes techniques for validating that a mission store comples with the interface requirements delineated in MIL-STD-1760. The purpose of this document is to provide methods for validating that an mission store's electrical interface comples with the mission store interface (MSI) requirements of MIL-STD-1760. This document provides a modular, independent set of methods for each of the requirements in MIL-STD-1760 that applies to mission stores. The methods herein apply to the auxiliary (AUX) interface as well as the primary interface of MIL-STD-1760.
