scope:

Use/relationship:

The interface control specification defines the physical and functional interface, parameter requirements between interconnecting, interacting, or co-functioning systems, system segments, and assemblies. It is used as a top level control document governing the design of the interfacing elements of the system/segment.

This Data Item Description (DID) contains format and content preparation instructions for the data product generated by the specific and discrete task requirement as delineated in the contract.

This DID is applicable to systems and equipment development contracts involving hardware-to-hardware and hardware-to-external factors (facilities, mission elements, . etc), interface conditions. For hardware-to-software or software-to-software cases, DI-CMAN-81248A, Interface Control Document, DI-IPSC-81434A, Interface Requirement Specification, or DI-IPSC-81436A, Interface Design Description shall be used.

When the complete interface requirements shall be reflected on an interface control Drawing and installation drawing as described in DOD-STD-100C, use DI-SESS- 81000C, Product Drawings and associated lists.

This DID supersede DI-CMAN-81314.
