BLOCK 3-DATA DESCRIPTION:

  1. The Shock Test Reports shall document the results of equipment shock tests, post-shock test inspections and functional tests to confirm that tested items meet the requirements of the contract.
  2. Shock test reports shall contain the following three sections: 
    1. Test Installation and Conduct. This section describes the test installation, conduct, and results of the test and shall include: 
      1. Description of material, size, and type of hold-down bolts (and of any other hold-down or locating devices) used to secure or locate the tested items to their foundations or test fixtures during shock tests. 
      2. Clear photographs of each equipment mounting configuration used during the shock test. 
      3. A drawing of the fixture. Modifications to standard fixtures may be submitted as marked-up drawings. 
      4. If shock test instrumentation is employed, a description of such instrumentation and a clear copy of data recorded during the test shall be submitted with the report. 
      5. Reference to the applicable equipment specifications or acquisition document including the applicable revision and date of issue shall be submitted with the report. 
    2. Post-Test Inspection. This section shall describe the conduct and results of the post-test inspection to confirm that the items meet the requirements of the contract. 
    3. Acquisition Requirements. This section shall state the applicable ordering data specified in the acquisition documents. This section shall include the Shock Test Procedures and the acceptance criteria of the item tested. For each item of damage or malfunction that occurred as a result of shock testing, include a recommended design modification with supporting rationale, to achieve acceptable shock resistance and correct any deficiencies found during the test or the post-test inspection process. In addition, include supporting documentation that the damage or malfunction in question does not violate applicable shock test acceptance criteria. Where matters involving shock test failures were resolved with the acceptance authority prior to submission of the test report, a record of these agreements shall include detailed descriptions of any damage incurred during each blow or shot and, where practicable, clear photographs of each instance of damage. This section shall also describe in detail any design modifications, repairs, or adjustments made to the item during shock tests or prior to post-test functional testing, and shall provide the equipment identification information requirements as specified in the contract.
