This document establishes techniques for validating that a mission store complies with the interface requirements delineated in MIL-STD-1760.

Purpose:

The purpose of this document is to provide methods for validating that an mission store's electrical interface complies 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.

Application:

The methods herein apply to initial validation of a store design to the requirements of MIL-STD-1760 and are expected to be conducted as part of store design validation (as opposed to qualification test, quality conformance test, flight line test, etc.). The methods contained in this document are sufficient to cover the Class I interface. Mission stores with Class II MSIs will use the appropriate subset of these Class I methods.

Tailoring:

The methods contained herein are general methods for conducting mission store validation and, as such, do not provide detailed procedures for these methods. It is intended that detailed procedures for validation of a specific mission store will be covered by tailored test plans and procedures prepared specifically for that store. These tailored test procedures would, for example, address those peculiar commands required to step through sufficient operations and states to demostrate compliance with the particular aircraft/store electrical interconnection system (AEIS) requirements under test.

Limitations:

The methods contained herein are used on MIL-STD-1760A through Notice 2. A future revision of this standard will address MIL-STD-1760B test techniques. In addition, this standard addresses testing compliance of a store to MIL-STD-1760 based on the assumption that all tests are conducted at the store's MSI connector and measurements of store performance occur only at this MSI connector.

Identification System:

The test methods contained in this document are designated by an alphanumeric identification scheme. Each method is identified by a three alphabetical character combination followed by a three digit number. The meaning of the first three individual letters is:

a. HBW: High Bandwidth Interface

b. MUX: Digital Multiplex Data Interface

c. LBW: Low Bandwidth Interface

d. REL: Release Consent Interface

e. INL: Interlock Interface

f. ADR: Address Interface

g. GND: Structure Ground

h. DCP: 28 V DC Power Interface

i. ACP: 115 V/200 V AC Power Interface

j. HVP: 270 V DC power Interface

k. FOC: Fiber Optic Interface

l. INT: Initialization

m. CON: MSI Connector

n. COM: Communication Rules

o. MSG: Messages on the Digital Multiplex Data Interface

The three numbers following the letter code is a sequentially assigned number such that numbers 101 through 199 are for aircraft station inteface (ASI) requirements and 201 through 299 are for mission store interface (MSI) requirements. When applicable, the letter following this three digit number is the test method revision letter. For example, HBW201 represents that original version of the first test requirement for the mission store high bandwidth interface while HBW201A represents the first revision of that requirement.
