Test Requirements Document (TRD)

The TRD defines test performance, test conditions, diagnostic requirements, and support equipment to fault locate, align, and verify proper operation of an item under test. It is used in the preparation of test packages (e.g., tapes, tape manuals, and interface items, etc.) or test procedures for test equipment.

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

This DID is applicable to engineering (developmental), preliminary qualification, qualification, and acceptance testing.
