Use & Relationship

The Shock Test Report provides the results of equipment shock tests, post-shock test inspections, and functional tests when equipment is subjected to the standard shock test methods in MIL-DTL-901. The report is used to determine whether tested items meet the requirements of MIL-DTL-901.

a. This data item description (DID) contains the format, content, and intended use information for the data deliverable resulting from the work task described in 3.1.8.7, 3.1.12, and 6.7.2 of MIL-DTL-901.

This report applies to shock testing equipment in accordance with MIL-DTL-901.

Sections 1 and 2 of the report will include input provided by the shock test facility and the activity performing post-shock test inspection. If the shock test facility and post-test inspection facility are other than the contractor, arrangements to ensure that this input is obtained are required.

b. Test reports for alternate shock test vehicles/machines shall be as required by the Technical Authority.

c. This DID supersedes DI-ENVR-80708.
