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 supersedes DI-CMAN-81314.

Preparation Instructions

1Reference documentsThe applicable issue of the documents cited herein, including their approval dates and dates of any applicable amendments, notices, and revisions, shall be as cited in the current issue of the DODISS at the time of the solicitation; for non DODISS-listed documents, as stated herein.

2FormatThe interface specification shall be prepared on 8 1/2 x 11" paper (metric size A4). It may be prepared as a multi-part, book form document as appropriate to the complexity of the interface(s) to be defined. It shall contain the following (see figure 1 for an outline of the specification structure and paragraphing):

2.1Front cover/title pageThe cover and title page shall contain the following:

2.1.1Specification numberThe expression "SPECIFICATION NUMBER" (all capital letters) followed by the assigned specification number shall appear in the upper right corner.

2.1.2DateThe expression "DATE" (all capital letters) followed by the issue date of the specification (day, month, year) shall appear directly under the specification number in the upper right corner.

2.1.3TitleThe title shall be a multi-line entry centered in the middle of the cover on title page as follows:

2.1.3.1The first two lines shall read (all capital letters)INTERFACE CONTROL SPECIFICATION FOR

2.1.3.2The third and subsequent lines shall include

2.1.3.2.1The nomenclature of only the primary system, segment or configuration itemThe nomenclature of only the primary system, segment or configuration item (including name and type designation and configuration item number) when more than one interfacing item is involved, or

2.1.3.2.2The nomenclature of each interfacing system, segment, or configuration itemThe nomenclature of each interfacing system, segment, or configuration item (including name, and type designation and configuration item number) where only two items are interfacing.

2.1.4Approval certificationApproval certifications shall be entered on the title. Name, signature and approval date shall be included as identified by the government.

2.2Section 1.0. Scope.The scope shall include:

2.2.1System/segment interface identificationThis section shall briefly describe the overall system, segment, or equipment to be addressed by the interface specification. It shall include a matrix diagram identifying each interfacing item, and show the origin and destination of each interface.

2.2.2Documentation organizationThis section shall describe the manner in which the specification is structured, and provides guidance on its use.

2.2.3Limitations and restrictionsThis section shall describe any limitations or restrictions to the use of the specification.

2.3Section 2.0 Applicable documents.All documents having a bearing on the system and segment interfaces shall be identified in sub-sections by the title number, and applicable data. This shall include:

2.3.1Military and Federal specifications, standards, and handbooks.

2.3.2Interface control documentationThis includes all related or referenced interface control drawings and interface control specifications.

2.3.3Other documentationThis includes any applicable industry or other documentation.

2.4Section 3.0, Interface requirements.This section provides the detailed description of the interface requirements. Each interface shall be separately covered in its own subsection (see figure 1), and include:

2.4.1Interface identification and description

2.4.2Functional interface specification details by parameter.

2.4.3Physical interface specification details by parameter.

2.4.4Environmental parameter details by parameter.

2.5Section 4.0, Quality assurance.This section shall identify and define the inspection and test requirements necessary to verify the designed end product complies with the interface requirements of section 3.0.

2.6Section 5.0, Notes.This section shall include non-binding administration information such as supersession data or other clarifying information. Each independent subject area shall be in a separate sub-section.
