SCOPE This document establishes techniques for validating that a mission store complies with the interface requirements contained in MIL-STD-1760 Revision D. 1.1 Purpose The purpose of this document is to provide method
22、s for validating that a mission stores electrical interface complies with the mission store interface (MSI) requirements of MIL-STD-1760. This document provides a set of modular, independent methods covering each of the requirements placed on the store by MIL-STD-1760. The methods contained herein a
23、pply to both the primary and auxiliary interfaces of MIL-STD-1760. 1.2 Application The methods herein apply to the 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, conformanc
24、e test, flight-line test, etc. The methods contained in this document are sufficient to encompass the Class I interface. Mission stores with Class II MSIs will use the appropriate subset of these Class I methods. 1.3 Tailoring The methods contained herein are general methods for conducting mission s
25、tore 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
26、 example, address those store-specific commands required to step through sufficient operations and states to demonstrate compliance with the particular aircraft/store electrical interconnection system (AEIS) requirement under test. 1.4 Limitations: The methods contained herein are based on MIL-STD-1
27、760. This AS is based on the assumption that all tests are conducted at the stores MSI connector and measurements of store performance occur only at this MSI connector. 1.5 Identification System: The test methods contained in this document are designated by an alphanumeric identification scheme. Eac
28、h method is identified by a three alphabetical character combination followed by a three-digit number. The meaning of the first three characters is: a. HBW: High Bandwidth Interface b.

GPS: GPS rf SAE INTERNATIONAL AS42701 4 OF 221The three numbers following the letter code is a sequentially assigned number such that numbers 101 to 199 are for aircraft station interface (ASI) requirements and 201 to 299 are
31、 for mission stores interface (MSI) requirements. When applicable, the letter following this three-digit number is the test method revision letter. For example, HBW201 represents the original version of the first test requirement for the MSI high bandwidth interface while HBW201A represents the firs
32、t revision of that test requirement. 2. REFERENCES The following publications form a part of this document to the extent specified herein. The latest issue of SAE publications shall apply.

The HBW validation matrix is presented in
43、Table 1. SAE INTERNATIONAL AS42701 12 OF 2215.2.2 Sequence of tests The mission store is not required to use any of the HB interfaces. For each HB interface that is not used, the requirements of MIL-STD-1760 for that interface can be satisfied by completion of validation method HBW201 and HBW202 onl
44、y. If any HB interface is used as either a source or a sink for HB signals, then all other validation methods must be applied to that interface.
